test_sleep() of test_eintr fails on VSTS/macOS. sleeps 200 ms, the process is supposed to get a signal every 100 ms, but the test says that the signal handler was not called during the test. All tests pass, the issue seems to be specific to macOS.

Maybe select() cannot be interrupted by SIGALRM on macOS?

I added the check (which fails) last week, ensure that the signal handler has been called at least once:
