What are your semaphore limits?
[tom at bofh tom]$ sysctl kern.ipc.semmni kern.ipc.semmns
kern.ipc.semmni: 10
kern.ipc.semmns: 60

That would be awesome. Additionally, Mono seems to have issues with
semaphores on amd64 jails. Right now it can't complete a build on the
pointyhat amd64 lines. That's how I first got bugged about this.

Worse, it's no good for pointyhat. It means kris@ need to chase down
the box and kill the build when this goes wrong.
Thank you for offering to look into this. :)
