[issue28779] set_forkserver_preload() can crash the forkserver if preloaded module instantiate multiprocessing classes

[Antoine Pitrou]

Antoine Pitrou added the comment:

Slight mistake in my explanation: the method in the base class raises ValueError, not NotImplementedError. Still, the basic explanation stands.

(that said, if you think this is out of scope for this issue, I can revert that part of the patch)
