[Twisted-Python] handling SIGCHLD

[Jason Rennie]

Two options:

   1. (as Itamar notes) use spawnProcess for all your process spawning needs
   2. reactor.run(installSignalHandlers = False) and do your own signal
   handling

For option #2, you'll almost certainly want to install SIGTERM and SIGINT
handlers which call reactor.stop().
