[Mono-dev] Patch for Processes.c on Mac OSX

[Tom Philpot]

We have a patch for io-layer/processes.c where Mono on Mac OSX crashes if
trying to lock a named mutex which is not owned by the current process. The
problem is that Mono on Mac does not correctly know how to enumerate
processes.

The attached program assumes that you have built it, it then launches itself
and takes a lock on a named mutex. The first instance also tries to acquire
the lock and crashes.

The attached patch fixes the issue for us.

Again, props to Martin Potter for the discovery and the patch.

Tom
