The failure definitely seems timing related. This change *seems* to work.
Since the failure isn't doesn't occur consistently, it's hard to tell.
Running these tests on Solaris in this order:
test_urllibnet test_operator test_cgi \
test_isinstance test_future test_ast test_logging
generally caused a failure (about 50% of the time) before the sleep.
I couldn't provoke the failure with the sleep.
This should really be cleaned up by using threading.Events or something
so it is not timing dependent and doesn't hang forever on failure.
want to wait forever if we don't receive the last message. But we also
don't want the test to fail if we shutdown too quickly. I can't reliably
reproduce this failure, so I'm kinda guessing this is the problem.
We'll see if this band-aid helps.
Not sure why/how _handlers/_handlerList is out of sync. This could
indicate a deeper problem.
In test_logging, the only absolutely necessary change to get working
was tcpserver.abort = 1. But we don't want to wait infinitely
to join the threads, so give a 2.0 second timeout.
There doesn't appear to be a need for a local abort variable
in serve_until_stopped, so just use the instance member.
Note the problem is only on HEAD, not in 2.4.
