The check is very non-obvious.
Don't how to make it more verbose and explicit.
If it's impossible -- I can live with it.

The ProcessPoolExecutor uses the multiprocessing (mp) module. The mp module is not functional when the mp.synchronize module cannot be imported and all the mp tests are skipped in that case. So we use here the same idiom used to skip the mp tests (i.e. test.support.import_module('multiprocessing.synchronize')) to skip this test when the platform sem_open implementation is broken or missing.
What about replacing the comment with:
Issue bpo-32126: The multiprocessing module used by ProcessPoolExecutor
is not functional when the multiprocessing.synchronize module cannot be imported.
