It was hanging on FreeBSD 7.2 recently:
http://buildbot.python.org/all/builders/x86%20FreeBSD%207.2%203.x/builds/4917/steps/test/logs/stdio
Oh, it still hangs on the latest version of the code. I opened #20495 to track
this bug.

I looked at last tests of FreeBSD 6.4 3.x between builds 4400 and 4432. The
builds 4401, 4408, 4416 and 4421 hanged but because of
check_interrupted_write_retry() of test_io, but none hanged because of
test_asyncio.
I also checked builds 3620..3643 of x86

The older FreeBSD systems have broken threading though, so we could just
disable the offending tests. I would not waste

This is a new issue, test_read_pty_output() is a recent feature which came with
a new test. The previous blocking test

OK, I have not seen the original issue in any recent builds either.

Hmm, test_signal_handling_while_selecting is a different one. Perhaps koobs can
investigate it :)

@antoine, would love some direction/guidance on ways to isolate.
For what it's worth, the incidence of this failure dropped sharply over the
subsequent 24 hours after the initial report. Could the relaxation of the
timers in 042deeeb703 have had an effect?
Thus far

Thus far I've checked out default, and ran test_asyncio at -j16 -j32
and -j64 with no reproduction
you can use -F to run the test forever.

I started strace ./python -m test -vF test_asyncio running under screen on
the RHEL6 buildbot (so it will keep running when I log out in a moment).
If I don't report back the results in the next day or two, ping the issue to
remind me to log back in and see if

Trace also child processes: add -f. And add maybe also timestamps: -tt.

New submission from Guido van Rossum:
There are still some problems with asyncio tests hanging on FreeBSD and
possibly other platforms.
While these were originally conflated with a hang on AIX, the root causes are
different; just the symptoms are the same (the test hangs forever and after
Guido van Rossum added the comment:
I haven't seen any such hangs. I've seen one test_asyncio failure on FreeBSD
6.4 3.x, which is the following weirdness.
