PR_Accept also takes a timeout argument. You may try using that to allow 
the function to return and do your shutdown afterwards.

Another option if you don't want to use a timeout is to use 
PR_Interrupt. You'll need the PRThread pointer of all the threads that 
are in PR_Accept, or in other NSPR blocking calls.

The later one is newer.
