SVN rev 187677 on 2009-01-25 07:24:34Z by jeff
Fix errors introduced when I rewrote select.
- Restructure selscan() and selrescan() to avoid producing extra selfps
when we have a fd in multiple sets. As described below multiple selfps
may still exist for other reasons.
- Make selrescan() tolerate multiple selfds for a given descriptor
set since sockets use two selinfos per fd. If an event on each selinfo
fires selrescan() will see the descriptor twice. This could result in
select() returning 2x the number of fds actually existing in fd sets.
