Yeah, 1.3 doesn't do the weird thing creating the second pipe and then
dup2()ing the original pipe fds into the new ones.  I don't know if
there's any real reason that's done or just some fallout from the way
the APR API works.  It would seem simpler to at least just dup() the
original fds instead and avoid the second pipe() call.

I've submitted backports for the last three commits to log.c.
