-1 not acceptable, you are looping back to dangling pipes, lingering
processes, non-running code, etc.  2.2.4 and prior code didn't even
run (piped loggers) on win32, remember?  Unix had it's own issues.

The 2.2.4-and-prior code was not acceptable, the proposed hack
is similarly unacceptable.  It was flawed on so many levels, the
proposed patch is as close as I can come to a comprise given the
broken state of APR (due entirely to your myopic interpretation
of the versioning policy, which I'm through arguing.)

Understand that is a /proposal/, it's still going to take me a few
days to resolve a test/aprpipe.c fault on win32 (one of three on
win32, of which the other two are well-known waiting on apr 2.0).
Actually about 8 last hours of work to fix that and vet this patch
as thoroughly as the first rounds, but I'm distracted thurs/fri
and I'll see how much attention I can apply to it before the
weekend.

I appreciate your desire to avoid "polluting" the unix path, but
it's really senseless to optimize code that's only invoked once/
process, and incredibly destructive to keep altering the code
paths as we saw over the past few months.  Keep a single impl.
We have it right in 1.3.0 and I've already flipped the 'apr 1.3
required' bits in httpd trunk.  Remember this audit already had
uncloaked a host of UNIX issues.  One code path.

If the proposed patch leaves dangling handles, it's because this
is a draft that I haven't finished vetting, I just wanted to get
it out there so folks would have a preview.  The final code will
be clean, a few redundant dups in a rarely executed code block,
but clean of dangling pipes on any platform.
