Comment(by klee):

 Further revised according to the comment :

 Line 50 "blocks" (waits syncronously without checking status); also [[BR]]
 half of a second may not be long enough if all memory was used up and
 [[BR]] there was excessive paging in/out from the swap file.  One
 alternative [[BR]] method is to check for the existence of the pid file
 periodically for [[BR]] a longer period (possibly parameterized), and if
 it is deleted, [[BR]] recheck that the twistd process has indeed exited
 else send SIGKILL. [[BR]]

 Otherwise, good refactor. :-) [[BR]]
