The epoll test failed on a buildbot. The test uses a short delay (10 milliseconds) and compare two different clocks: time.perf_counter() and select.epoll.poll(). I didn't expect a failure very the greatest delay, the test uses even shorter delay (the shortest is 0.1 ms).

The best would be to trace syscalls to check if epoll_wait() is called with a non-zero timeout, but tracing syscalls is overkill and too low level for such test.

It's maybe better to drop this unstable test? Unstable on our slow buildbots.
