- Allow the thread that called LdrShutdownProcess to forcefully acquire critical sections (the loader lock in particular).
This fixes the race condition where ExitProcess might terminate a thread holding the loader lock and subsequently call LdrShutdownProcess. That would then result in a deadlock because LdrShutdownProcess cannot acquire the loader lock.
This is a pretty ugly hack... but at least Windows does it the same way.
Fixes hangs after the summary line when running mshtml tests.
