While trying to compile Mono on an x86-64 with 4 cpus, I get two assertions
while bootstrapping (currently I am at r106855):

I turned the first into a g_warning:

** (../../class/lib/basic/mcs.exe:24932): WARNING **: ret != 0 in
DeleteCriticalSection, something is wrong?
**
** ERROR:(marshal.c:4657):mono_marshal_get_runtime_invoke: assertion failed:
(ret == 0)

Program received signal SIGABRT, Aborted.
