   Yeah.  What this means is that select() examines 
   the slots in the vector numbered 0, 1, ..., nfds-1.  
   If you pass `1' as nfds, then select() will only look 
   at the settings for fd 0.  This is a goofy interface.  
   Maybe we ought to use poll() instead.  I don't know.  I
   use select() since I have a bsd-ish background.

Ah! I see. Sorry, I think somewhere in the mists of time I did know
that... 

I've been dealing with java non-blocking in a variety of different
ways this week (nbio, jdk1.4 non-blocking io and this GCJ change) and
I got all confused.

poll seems to be accepted as being quicker... /dev/poll is used by
the NBIO project to make things really quick... I'm not sure to what
extent it matters doing things the way we are though.

It's probably more important to get the threading layer better.

I will probably investigate the use of poll by hammering
GNU-Paperclips running under GIJ.
