Hm, really?  For same-host processes, threads would
do the job nicely I'd say.  Or you could probably
use unix domain sockets (popen only really works on
Unix, so that's not much of a restriction).

Also note that often this is needed in the context
of a GUI app; there something integrated in the GUI
main loop is recommended.  (E.g. the file events that
Moshe mentioned.)
