This (and other bugs) is caused by locking problems inside the runtime.
When an appdomain is unloaded, all threads executing in the domain are
aborted. When a thread is aborted, it might be holding unmanaged locks,
like a lock on the domain. Since the runtime does not have finalizers,
these locks remain locked by the dead thread, leading to a deadlock.

+I've analyzed this a bit. Looks like the timeouts in "appdomain.c"
+(one second for thread aborting and finalizing) are too small.
+When I boosted them to 10 seconds, my problem disappeared.
+I'm attaching the patch. Can you consider applying it as it fixes many
+problems with NAnt and NUnit on Linux?
