Eh?  If the program exits, it should clean up its own sockets.  Can't you
fix the program, instead of trying to write this workaround wrapper?

If you can't, then it sounds like you want a child process that has the
ability to interact with a terminal device (i.e. is NOT a background job
created by a shell).  That sounds like a job for C.
