This is because scripts (at least on XEngine) start unsuspended - deceptively the ResumeScripts() calls in various places in the code are actually completely redundant (and useless).
The solution chosen here is to use a copy of the SP attachments and not have the list locked whilst creating the scripts when an avatar enters the region.
This looks to address http://opensimulator.org/mantis/view.php?id=6557
heartbeat timestep when running the physics engine on a separate
thread. This reduces the occurance of heartbeats that happen when
there is no physics step which is seen as vehicle jerkyness.

is fetched. This fixes a 'pure virtual function' crash when changing
physical state of complex linksets that include many meshes.
thread. Off by default until more testing.
Setting "[BulletSim]UseSeparatePhysicsThread=true" causes the physics
engine to be called on its own thread and the heartbeat thread only
handles the reporting of property updates and collisions. Physics frame
rate is about right but physics execution time goes to zero as accounted
by the heartbeat loop.
This is possible where there is more than one scene (multiple copies of the same script engine) and/or more than one script engine being used.
These operations are not thread safe and could be leading to the exceptions/problems seen in http://opensimulator.org/mantis/view.php?id=6651
This also prevents a small race condition where more than one AsyncLSLCmdHandlerThread could be started.
Because of a typo, this wasn't being done at all - now the 'default' value as described in OpenSimDefaults.ini of 10m is passed (vivox_channel_clamping_distance)
Thanks to Ai Austin for spotting this.
This purports to fix the issue described in http://opensimulator.org/mantis/view.php?id=6653 where the camera can end up following the requested sit prim rather than the actual.
The original spot was by Vegaslon, this commit just goes about it in a slightly different way
This commit also makes m_requestedSitTargetUUID to be the actual UUID, which is consistent with m_requestedSitTargetID which was already doing this.
However, this adjustment has no practical effect since we only currently need to know that there's any requested sit UUID at all, not which one it is.
The UMMTGUN form of Unknown User seems to appear because a viewer sometimes sends a UUIDNameRequest UDP request that fails to find a binding.
However, in theory the incoming agent should have made that binding before any such request is triggered.
So moving this binding to an earlier point in the process to see if this makes a difference.
Unknown user name is also updated to UserUMMTGUN2 - if you see the old name then you need to clear your viewer cache.
This relates to http://opensimulator.org/mantis/view.php?id=6625
if the mesh asset specifies physics hulls, BulletSim will fetch and
use same rather than approximating the hulls. If physics hulls are not
specified, the representation will fall back to the regular physics mesh.
which recompute GImpact shape bounding box after creation as Bullet
doesn't do that itself (something it does for nearly every other shape).
Now, physical prims without cuts become single mesh convex meshes. Physical
prims with cuts become GImpact meshes. Meshes become a set of convex
hulls approximated from the mesh unless the hulls are specified in the
mesh asset data. The use of GImpact shapes should make some mechanical
physics more stable.

hashes for the purpose of accurately responding to AgentTextureCached
packets. There is a change to IClientAPI to report the wearbles hashes
that come in through the SetAppearance packet. Added storage of the
texture hashes in the appearance. While these are added to the
Pack/Unpack (with support for missing values) routines (which means
Simian will store them properly), they are not currently persisted in
