The Multiprocessing docs specifically say that Queue is process- and thread- safe: https://docs.python.org/3/library/multiprocessing.html#exchanging-objects-between-processes.
But this information is not given for the various synchronisation primitives and such (Lock, Semaphore, Event, etc)
Are they thread-safe? Should the docs say whether they are or are not?

Here's an example where such documentation may have helped: https://bugs.python.org/issue40860
