I've done some more investigation and I've filed a new bug and marked
the old one as a duplicate of the new one:
It looks like the problem has to do with garbage collection and
threading and it should effect just about anybody that uses threads
under Mono on OS X. I attached a rough GC patch to the bug that
halves the number of ports leaked in some situations, but does not
entirely fix the problem. The patch also has a lot of whitespace
changes I made so I could properly read the code (sorry about that).
At this point, I'm not sure what else to do. I'm wondering if the
rest of the leaks could be caused by another place where
mach_port_deallocate() isn't being called when it should be. I'm no
mach expert, so I'm not sure where else to look.
