Alternatively, use comm <http://wiki.tcl.tk/comm> to avoid having to deal
with explicit socket-handling, fileevent-handling and other necessary
bookkeeping. Each side would then just call the appropriate procedures
on the other side.

comm is so useful and robust that I normally advise folks around me to
think about using comm first for IPC, only falling back on manual socket
stuff for the really complicated stuff.
