[New-bugs-announce] [issue12981] rewrite multiprocessing (senfd|recvfd) in Python

[Charles-François Natali]

New submission from Charles-François Natali <neologix at free.fr>:

Now that sendmsg()/recvmsg() are exposed in socketmodule, we could use them to replace the ad-hoc FD-passing routines used by multiprocessing.reduction.
Antoine suggested adding sendfd()/recvfd() methods to socket objects, but I'm not sure about this, since those only make sense for Unix domain sockets.
Two remarks on the patch attached:
- this removes sendfd()/recvfd() from _multiprocessing (but AFAICT those were never documented as part of the public API)
- EOF/invalid data received result in a RuntimeError
