SPUG: Forked Children talking back to the parent?

[John Labovitz]

To handle the case of a child "hanging," you might consider using
IO::Select (a front-end to the select(2) system call) to manage the
connections.

With IO::Select, you can "watch" several file-handles at once, and
then read only from ones that are ready.  You can also specify a
timeout value, so if none are ready to read, you can figure out which
haven't responded for a while and kill() them (or whatever).

There's an example program in the manpage for IO::Select (which comes with
standard perl, btw).
