processes

I think this part of the bug is much more unlikely to cause problems than
#3231, as it should only affect you if you're creating processes from
multiple threads, and even then it might not cause a problem, because the
only effect is to unnecessarily inherit a pipe Handle or two. There's
also a workaround: do your own mutual exclusion. So I'm not suggesting we
merge this into 6.10.4.
