Marc Slemko (another apache developer) wants to do this with FreeBSD and he's going to add a socket option for it. That should deal with both of your issues.
BTW I looked at the linux kernel code and it does look like it's safe to remove the #define USE_FCNTL_SERIALIZED_ACCEPT from the LINUX section of apache's src/conf.h. This was previously added probably because of situations where linux would get confused with multiple processes blocked in accept() on the same socket.
But the kernel looks a little inefficient -- all processes blocked on accept() are awakened when a new socket is ESTABLISHED. It looks a bit difficult to awaken only one... unless an accept wait_queue is created. Dean
