Yeah, that was a failure from me, so I tend to be rather very careful
about anything related to Windows.  However, after that we have added 
40cfe86 about which nobody has complained yet, and the number of
buildfarm failures about pg_ctl concurrency on HEAD has gone down to
zero since (perhaps I am missing something?).

So, instead of trying to invent a new solution only for stable
branches (which may have its own bugs we would need to deal with only
on stable branches, and only for Windows), why don't we just try to
move forward into back-patching those pieces?  Or it happens that we
still have some potential failures on HEAD and REL_12_STABLE which
would justify some extra handling?  In this case, I would recommend
that we focus on HEAD as a first step, and put things in order there.
