From what I've seen we are more likely to hit the per-system file handle
limit when all separate forks open the same files over and over again,
so as the number of processes grows we will be worse off than usin the
same file handles for all connections in threaded mode.

This whole thread started with a notion that this has already been done
once and the idea was to investigate what could be brought over to main
forked-only (the threaded version could be forked at the same time)
codebase.
