Apache just has all of the worker processes call accept() on the
socket, and whichever one the OS hands it off to gets the job. The
problem is harder for us because a backend can't switch identities
once it's been assigned to a database. I haven't heard an adequate
explanation of why that couldn't be changed, though.
