LP1204123 Set SIGCHLD handler to DEFAULT for children (perl)
Remove the special SIGCHLD handler applied to the parent/listener
process from spawned child processes (drones) by setting child handler to
DEFAULT. Otherwise, if an OpenSRF drone process spawns a sub-process,
the drone will execute the SIGCHLD handler meant for the Listener when
the sub-process dies, wherein hijinks ensue.
