Really simple.  Async.  No verification.  Application will handle 
exceptions.

Basically, the current need is for a process that has accepted a socket 
connection request to spawn a worker process, notify the worker process 
of some data, device name and such.  The worker will connect to the 
device, then tell the parent (listener) process it has the device open, 
and the parent can close the device channel and forget about the connection.

Was using a BASIC OPEN for the mailbox.  Real crude and sync, and I 
don't like to mess with resource wait mode from inside BASIC.  Might 
have unexpected consequences.

Might get a bit more complex later, this is just a prototype, proof of 
concept.  Took the summer off, but last time I was working on it, my 
crude mailbox stuff had a problem.  I'm used to cutting a bunch of 
corners when I'm prototyping stuff.
