Why would someone want the current (as of last night) behavior?  IMO
it's useless.  The distinction with non-blocking mode is very minimal.

Hm, but a zero really does smell more of non-blocking than of
blocking.  It would also be inconsistent with the timeout argument to
select(), which currently uses None for blocking, 0 for non-blocking,
and other positive numbers for a timeout in seconds -- just like
settimeout().
