[Mono-list] mscoree.dll crash

[Kornél Pál]

Hi,

MSVCRT is calling CorExitProcess on exit if mscoree.dll is loaded. 
mono.dll is hooking some mscoree.dll exports (including CorExitProcess) 
to itself but is not removing these hooks on unload.

I suggest you to keep an extra reference to mono.dll so that it will not 
be unloaded until process termination.

This is a bug that should definitely be fixed but I will need some time 
to come up with an optimal solution.
