multiprocessing is missing several files

Yup. All of these are undocumented, so relatively low pri (as per slightly outdated checklist in #4545 , issue also contains a script to get list of missing modules in stdlib).

Once the open merge requests are completed, I'll move onto the next series of files. I'm trying to avoid creating too many merge requests at any one time.

I seem to have missed where the script was in the linked issue to locate files/modules without stubs, but I'd be happy to address other modules if I can identify how to locate those.

Moving onto last two hopefully today, depending on my meeting schedule. If all goes to plan this should be able to be closed by the end of the week

This will be fixed when the remaining PR's are completed.

Note though that there are some additional opportunities in multiprocessing to expand stubs further, if interested
