[FAIL]: twisted.test.test_ssl.BufferingTestCase.testOpenSSLBuffering

Traceback (most recent call last):
  File "/home/radix/usr/lib/python2.4/site-packages/twisted/test/test_ssl.py", line 369, in testOpenSSLBuffering
    self.assertEquals(client.buffer, ["+OK <some crap>\r\n"])
twisted.trial.unittest.FailTest: [] != ['+OK <some crap>\r\n']
-------------------------------------------------------------------------------

The test uses reactor.iterate in a super lame way, and if I change the following line:

while i < 5000 and not client.buffer:

To have a larger upper bound (say, 50,000) it very reliably passes. It shouldn't be doing iterate explicitly.

This should close #2918 too.

_runTest could use a docstring. Other than that, looks good. Merge when ready.

(In [23717]) Merge test-ssl-iterate-2374

Author: therve Reviewer: exarkun Fixes #2374 Fixes #2918

Remove reactor.iterate calls from test_ssl.
