Subject: [PATCH] * add keepopen.py, which holds a file open until it recieves
 a   SIGUSR1, then it reads the file and closes it, returning an error   if
 anything fails.

* replay_single.sh/test_8 uses keepopen to test close replay after
  unlink. So far, the test actually passes, but from reading the log I
  can see the MDS_CLOSE is not replayed, because it doesn't get a
  transno. Not sure how to actually test for this.
