I'm afraid it's worse than just the man pages.
After thinking for a fleeting moment that what you were
saying made no sense, then thinking some more and thinking
it did make sense, I went back to my standard bible
"Advanced Progamming in the Unix environment" (Stevens &
Rago), which actually explicitely states ("select and
pselect functions", p475):
"With [select's] return information, we can call the
appropriate I/O function (usually read or write) and know
that the function won't block."
I guess this should read "call the I/O function and know it
wouldn't have blocked if we'd called it instead of calling
select".

If even the reference litterature gets it wrong...
