Crash when unloading domain. I am getting this crash when unloading domains. It
happens when a fairly large set of dll's is loaded and several methods were
called before the domain is unloaded. It doesn't happen if none of the dll's
were invoked prior to unloading.

I haven't been able to reproduce the crashbug outside of our application yet.
