   Here SuS speaks about OPEN_MAX, not sure if OPEN_MAX corresponds to the
   current ulimit or to the absolute maximum (to me it sounds more like our
   NR_OPEN).

Right, and our equivalent is "NR_OPEN".

Ok, I think I see what you and Tim are trying to say.
I'm thinking in a select() minded way which is why I didn't
understand :-)

Yeah, the check can be removed, but anyone who cares about
performance won't pass in huge arrays of -1 entries if only
the low few pollfd entries are actually useful.

Later,
