Because the timeout was 30 minutes, we missed where test_ssl hangs on "x86 Windows7 3.x":
--------------
...
[259/354] test_filecmp
[260/354] test_ssl

command timed out: 1200 seconds without output, killing pid 3012
SIGKILL failed to kill process
using fake rc=-1
program finished with exit code -1

remoteFailed: [Failure instance: Traceback from remote host -- Traceback (most recent call last):

It looks like this buildbot has some network issues:

 * build 2877 failed on test_ssl
 * build 2872 failed on test_poplib
 * build 2866 failed on test_ftplib
 * build 2865 failed on test_smtplib
 * build 2864 failed on test_socket
 * ...

Note: build 2869 failed on test_multiprocessing.
