On a whim, I tried watching the port count with the racy.c code from  
bug 77470 and it seems that it causes a similar (possibly the same)  
port leak. I've filed a bug here:


I've also identified a few spots in the darwin_stop_world.c where it  
looks like mach_port_deallocate() isn't being called where it should  
be. I've written a patch, but I had to leave the office before Mono  
finished building. I have a scenario in my mind where the bug I filed  
and the mach_port_deallocate() thing are both related. I'll know more
