+You should call this function if you need to take care of special
cleanup
+functions _after_ the line has been hungup.
+
+You must carefully check all the returns codes to terminate
properly on
+returned -1 (line hangup) values, otherwise a lot of stale
processes remain on
+your system running.
+
+WARNING: Modifies Perl $SIG{"HUP"} and $SIG{"PIPE"} handlers!
When exactly is SIGPIPE sent? When is SIGHUP sent in such a scenario?
IIRC SIGPIPE is sent if a process is writing to a pipe and that pipe
is broken, as in the receiving process dies.
