Use spawn in _compat_test.py to avoid fork problems #6374

Closed maffoo closed 9 months ago

Fixes #6373.

Note that using multiprocessing with "spawn" is significantly slower than either "fork" or "forkserver", but it ensures that the subprocesses are isolated so is significantly safer. We can switch back in the future to improve performance if we can work out the issues, but for now I think using spawn is more robust.
