After mono crashes, it spins, using 100% of cpu and is unkillable except via
-9.  The exact cause of the crash can vary and be one of many, but the critical
problem is that spinning on CPU is much worse than exiting.

Easy way to trigger the bug:
sudo rm -r .wapi
sudo mkdir .wapi

This triggers the _wapi_shm_file_open assertion failure.  But instead of
exiting after printing the message, the mono process gets stuck.

Please note, this bug is NOT about .wapi.  That's only a simple way to trigger.
