I'm embedding Mono at runtime so I build Mono with Cygwin and use it
from mono-1.dll. I once tried building it with VS2005 but found that
it's easier this way.

You said earlier that mono_runtime_exec_managed_code also shuts down
the runtime, even if it does that, is it a problem in my case? Because
when I run that program two times everything still works fine but I
get that "The request timed out". Is it because that runtime shutdown
or something else?
