This appears to be the same problem as ticket:5024.
I just upgraded to Snow Leopard and reinstalled all of my ports "port
uninstall installed; port install <those I care about>".
When ogg123 finishes a file, it doesn't exit, nor can I kill it will
ctrl-c or kill -15, I need to use kill -9. Ctrl-z doesn't suspend it
either. I suspect there's a deadlock in the signal handler.
Here is the inspection trace from activitity monitor:

I've also noticed that when xemacs execs a process xemacs locks up.
Perhaps there is is a common problem between the two and how threads are
handled in Snow Leopard.
