From what I can see it's down to bi-directional read/write on a FIFO.
Typically a FIFO expects a reader and a writer (it's just a filesystem
PIPE).
Therefore we should be using two file descriptors, one for read and one
for write. Not one file descriptor and using read/write. That's the
Linux'ism
we're talking about here.
Yes, ACK that entirely. However an argument could be made that
because BSD, Linux, and everything else with any significant user-base
have arrived at sufficiently similar non-POSIX behaviors, Gentoo's
able to get away with it. The matter has been discussed, and a
consensus was reached among the devs that it was an OK compromise.
I think if you re-coded the multiprocessing stuff to work the same,
without exploiting this platform quirk or making a big mess of the
code, and posted your patches to your bug (and a separate one for
portage) you could probably get your patches in. But just filing a
bug and expecting someone else to fix it is probably not going to
work, IMO.
Fixed for my OS, and it still works on Linux.
Patches uploaded.
Alan.
