  Speed up this test by about 99%.  Remove sleeps and replace with events.
  (This may fail on some slow platforms, but we can fix those cases which
  should be relatively isolated and easier to find now.)
  Move two test cases that didn't require a server to be started
  to a separate TestCase.  These tests were taking 3 seconds which
  is what the timeout was set to.

  The contains function raised a gcc warning. The new code is copied straight from py3k.

  Add a timing flag to Trace so you can see where slowness occurs
  like waiting for socket timeouts in test_smtplib :-).

  Patch #1691070 from Roger Upole: Speed up PyArg_ParseTupleAndKeywords() and improve error msg
  My tests don't show the promised speed up of 10%. The code is as fast as the old code for simple cases and slightly faster for complex cases with several of args and kwargs. But the patch simplifies the code, too.
