[issue39763] distutils.spawn should use subprocess (hang in parallel builds on QNX)

I am confused.

The bot complains nearly immediately about missing _socket

Following modules built successfully but were removed because they could not be imported:
_asyncio

ModuleNotFoundError: No module named '_socket'

while if I use my (now closed) pr18847 I do not get the results immediately - it starts the whole test series, and then fails - but not because _socket does not exist, instead:

0:00:48 [ 53/420/2] test_socket failed (30.4 sec) -- running: test_multiprocessing_fork (48.3 sec)

In short, stumped...
