in reply to 4 arg select as an alternative to Time::HiRes ?

You could also try this for size: 
BEGIN { *CORE::sleep = sub(;$) { select((undef)x3, shift) } }

sleep 0.75;

    I can never get select to accept (undef)x3,$time?

    I also found that substr won't accept an array for its argument list either?

      You are right about substr. Unfortunately, select seems to have some special magic; even the error message you get is unique to it.

      One more thing to remember..

        It's probably too obscure for general use, but I did just 'discover' that you can do 

        select((),(),(),.125);
