On NetBSD by default, the following tests do not finish in > 1h:

1:07:13 load avg: 0.00 running: test_compileall (1 hour 7 min), test_multiprocessing_fork (1 hour 7 min), test_concurrent_futures (1 hour 6 min)

Defining HAVE_BROKEN_POSIX_SEMAPHORES fixes this, and they finish:

0:00:32 load avg: 10.63 [408/427/17] test_compileall passed ...
...
0:02:37 load avg: 3.04 [427/427/22] test_concurrent_futures passed (2 min 33 sec)

The last one fails:
test_multiprocessing_fork

with most of the subtests failing like this:

ERROR: test_shared_memory_SharedMemoryServer_ignores_sigint (test.test_multiprocessing_fork.WithProcessesTestSharedMemory)

I think this is a separate issue, so I'd like to define HAVE_BROKEN_POSIX_SEMAPHORES for now.

This has been done in pkgsrc since at least python 2.7 (in 2011), I haven't dug deeper.
