move the lock out a bit further in the ProccessAssetCache loop to reduce 

the number of times we are going to take this lock in a row (which is
just wasted resource), and to keep us from attempting to array access a
list which might be changing right now.  Extremely curious if this helps
prevent some of our mono segfaults.
