I need to poll the device every 3 seconds.  If I move the loop outside
of the accept, won't it just call Send_Status_Req procedure one time,
then finish the task?

Surely there must be a mechanism similar to C's pthread that allows me
to start a thread and let it worry about itself, while the main thread
continues processing.  All I'm seeing here is that the task is run in
parallel to the other code in the Handle_Msg procedure.  I wan't that
procedure to finish up, and let the rest of the program continue to
run, all with Poll_For_Status running in the background.
