[Mono-dev] [PATCH] Add mixed-mode assembly support on Windows (now build with cygwin as well)

[Kornél Pál]

Hi,

Previously I forgot to try _CorDllMain to load the runtime when it hasn't 
been loaded yet. As a result I found that thread_started_event in 
mono/mono/metadata/gc.c causes a deadlock in this situation because 
_CorDllMain is callled while the OS loader lock is held by the current 
thread and no new threads are started while OS loader lock is held. After 
examining the purpose of thread_started_event I found that unlike the 
comment states it is not required at all so I removed it completely. This 
will make startup faster as well. I also checked that finalizer_thread is 
called and reaches SetEvent (shutdown_event) at the end.

My test confirmed that Mono even supports mixed-mode assemblies with 
exported symbols if they were native DLLs just like MS.NET does.
