... I have disabled the leak warning for:

LEAKYTESTS="test(cmdline|ctypes|filecmp|socket|threadedtempfile|threading|urllib2) This is an attempt to reduce the spam. Would people rather me reduce this list so we can try to find the problems? The test runs 2 times per day. Sometimes it gets stuck. But the most you should ever receive is 2 mails a day.

I see so much email that 100/day more or less from any particular source wouldn't be noticed.

It's possible that increasing the repetition count for some of these tests would make them easier to understand. For example, test_cmd_line settles into a very regular pattern on my box when run more often:

C:\Code\python\PCbuild>python_d -E -tt ../lib/test/regrtest.py -R:20: test_cmd_line test_cmd_line beginning 25 repetitions 1234567890123456789012345 ......................... test_cmd_line leaked [36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36, 36] references 1 test OK.

IOW, after 5 "warmup " runs, each of the 20 following runs leaked 36 refs. That may be unique to Windows (especially since all the leaks here are due to the tests that call CmdLineTest.exit_code()).
