[issue1040026] os.times() is bogus

[Malte Helmert]

Malte Helmert added the comment:

Here is a patch that adds a test case to test_posix.py. This is ignored
on Windows, as it requires fork.

There is a trade-off: If WAIT_TIME isn't large enough, small
irregularities in the process scheduler might cause this to fail. If it
is too large, the unit tests will take long for everyone.

Currently, WAIT_TIME is 0.1 seconds and the tolerance in the assertion
is about 5%, which works well for me. Not sure how this behaves on very
busy machines.
