Detect fork and do not reuse forked connections in drb
This associates each DRbConn with a pid, and if the pid changes,
it closes any DRbConns in the pool with a pid that no longer
matches. This fixes DRb servers from sending messages intended
for one client to another client after forking.
Fix some DRb issues (#2552)
Also fix a bug in rescue clause of any_to_s because sprintf
does not handle the %l modifier.
Fixes [Bug #7833]
This allows for normal TCP shutdown (fin-ack-fin-ack instead of
fin-ack-push-rst).
