def __init__(self, reactor, executable, 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.)
