def __init__(self, reactor, command, args, environment, path, proto, uid=None, gid=None, usePTY=None): (source)

overrides twisted.internet.abstract.FileDescriptor.__init__

Spawn an operating-system process.

This is where the hard work of disconnecting all currently open files / forking / executing the new process happens. (This is executed automatically when a Process is instantiated.)

This will also run the subprocess as a given user ID and group ID, if specified. (Implementation Note: this doesn't support all the arcane nuances of setXXuid on UNIX: it will assume that either your effective or real UID is 0.)

def reapProcess(self): (source)

Try to reap a process (without blocking) via waitpid.

This is called when sigchild is caught or a Process object loses its "connection" (stdout is closed) This ought to result in reaping all zombie processes, since it will be called twice as often as it needs to be.

(Unfortunately, this is a slightly experimental approach, since UNIX has no way to be really sure that your process is going to go away w/o blocking. I don't want to block.)
