I have a file server coded in J.  It listens on a port and responds to 
requests.

This morning while testing I canceled the J window that the server was 
running in, and started it up again.  It failed because it said the port 
number was in use (EADDRINUSE, 10048).

This means that when the previous J task was terminated, it was somehow 
left bound to its port.  This could be a problem in the field.

I would think that this is an OS bug (Windows XP), but in case there is 
something that I or j.exe could do to prevent this, I'm reporting it here.
