In rtems-19990528, sbwait sets SB_WAIT in sb_flags. sowakeup checks
it. Why doesn't socket_select set it?

I don't know that this is a bug--I haven't tried to create a test
case. However, it certainly looks odd.

Yes, there's a bug there. Sorry about that.
It was introduced when I did some cleanup on the sleep/wakeup handling
in rtems_glue.c.
