Failure seen on the Windows XP buildbot:

https://buildbot.python.org/all/#/builders/45/builds/288

0:02:14 [ 35/404/1] test_socket failed
test test_socket failed -- Traceback (most recent call last):
  File "d:\cygwin\home\db3l\buildarea\2.7.bolen-windows\build\lib\test\test_socket.py", line 1020, in testRecv
    self.fail("Error trying to do non-blocking recv.")
AssertionError: Error trying to do non-blocking recv.

In fact, the master branch still uses the weak 100 ms sleep as synchronization primitive :-(

Attached PR replaces time.sleep() with a threading.Event().

Ok, test_socket should depend a little bit less on time now ;-)
