On x86_64, python-minimal build hangs when running the tests:
$ guix build /gnu/store/gifx79qc77zk88z6gnabj81iksp1xaj9-python-minimal-3.8.2.drv
[...]
1:06:10 load avg: 1.31 running: test_multiprocessing_forkserver (14 min 42 sec)
It's reproducible every time.

Where does this derivation come from? I can't seem to find it on the
machines I have access to.

I can also reproduce this on the version-1.3.0, building for
armhf-linux. Another release blocker :-/.

So… no problem? Or perhaps it’s a function of the number of cores or
something? (Here that’s with 2 cores/4 threads.)

For me it seems to happen only when using QEMU transparent emulation,
e.g. to build it for armhf-linux on an amd64 machine.
Danny, are you still able to reproduce this problem from the master
branch, without using QEMU emulation?
Thank you,
Maxim

A first RC1 release candidate with the 5 supported architectures could
be produced without this bug being a blocker. The key was in using real
hardware rather than QEMU emulation.
Unblocking.

Closing, as I don't think tracking QEMU-induced build problems is in
scope for our bug tracker.
