I've written a patch that sort of implements the functionality that makes the
most sense to me. The problem is it only works right for the first entry.
It's kind of wonky and I'm not entirely sure how it behaves, nor do I know the
cause of the bug, but
Armin Rigo added the comment:
The patch looks good to me. It may break existing code, though, as reported on
https://bugs.pypy.org/issue1595. I would say that it should only go to trunk.
We can always fix PyPy (at Python 2.7) in a custom manner, in a bug-to-bug
compatibility mode.

I'm OK with both of Victor's suggestions but personally slightly prefer

New submission from Lars Buitinck:
The new multiprocessing based on forkserver (issue8713) looks great, but it has
two problems. The first:
set_start_method() should not be used more than once in the program.
The documentation does not explain what the effect of calling it twice would
be.
