* A hacky attempt at resolving mantis #4260. I think ODE was unable to allocate memory, and therefore the unmanaged wrapper call fails or worse.. there's some unmanaged resource accounting in the ODEPlugin for ODECharacter that isn't being done properly now. 

* The broken avatar may not be able to move, but it won't stop simulate from pressing on now.   And, the simulator will try to destroy the avatar's physics proxy and recreate it again...    but if this is what I think it is, it may not help.
