gdb session
In rare cases mono seems to go into an infinite loop upon shutdown (after the
managed Main method has finished).
I attach a gdb session where I've Ctrl-C'ed a few times and printing the
backtraces, the traces seem to indicate that thread 2 is the one looping.
I can provide login information to access the gdb session shown in the attached
file.

Architecture: amd64
Disabled: none
It's happend on both (slow) x86 and (faster) x64 machines, and when it happens
it seems to happen again easily if the previous processes are still running
(causing a lot of processes pegging the cpu).
