If this is agreeable, I can make an MR with this change, and add a test that `Poller` becomes fork-safe (on platforms that use `fork`).

> This would need to be something that the user can choose, as the default needs to stay as it is right now. I don't believe the suggestion I'm making...

(For what it's worth, I can't see how the failed check can possibly be related to this change?)

> The CI failure was spurious, and I've restarted it. The change looks reasonable, but could you please add an entry to the CHANGELOG? Done.
