it should, but I should note that for test 9 to fail, then either (or both)
tests 7 and 8 should first succeed; not that I'd seen any other test fail (after
I locally patched the perl path, of course) even when reordering them and
while making sure tests 1 and 2 run first to create the dependencies
for the rest

Peff, could you elaborate on your "load testing" setup? which could
give us any hints
on what to look for?, FWIW I hadn't been able to reproduce the problem anywhere
else (and not for a lack of trying)

that should help with the garbled output from stderr, AFAIK the
process API allows creating
a pipe specifically for that with would be better than redirecting
stderr into stdout.

the fact we got EBADF means that there is a problem somewhere though
in the way the
previous failure that closed stdout got handled (which should had been
most likely in
the call to die)


PS. upstreaming the PERL_PATH fix is likely to be good to do soonish
as I presume at least all BSD might be affected, let me know if you
would rather me do that instead as I suspect we might be deadlocked
otherwise ;)
