CVS commit: src/sys

Module Name:    src
Committed By:   rmind
Date:           Thu Jul  8 12:23:31 UTC 2010

Modified Files:
        src/sys/kern: sys_select.c
        src/sys/sys: fd_set.h lwp.h param.h selinfo.h types.h

Log Message:
Implement direct select/poll support, currently effective for socket and
pipe subsystems.  Avoids overhead of second selscan() on wake-up, and thus
improves performance on certain workloads (especially when polling on many
file-descriptors).  Also, clean-up sys/fd_set.h header and improve macros.
