I was thinking that the signal would mean 'time to go look at the usrspc cmd byte'. I think I'm going to read up on semaphores again and see if these will fill the bill. The unix sockets do create an object in IFS that you can see with WRKLNK. I'm not sure but I think they go away when the sockets are closed. I haven't used them but some packages on our system do.
