[New-bugs-announce] [issue22332] test_multiprocessing_main_handling fail on buildbot "x86 FreeBSD 6.4 3.x"

[STINNER Victor]

New submission from STINNER Victor:

The test requires SemLock which is not supported on FreeBSD 6.4. The whole test_multiprocessing_main_handling should be skipped on this platform.
