[Python-Dev] Drop the new time.wallclock() function?

Do you really want to add an obscure Boolean flag to the function just so that python can warn you that perhaps your platform is so old and so weird that Python can't guarantee that the performance measurements are to a certain _undefined_ quality?

Please note, that the function makes no claims to the resolution or precision of the timer involved.  Only that it moves only forward.  It is therefore completely and utterly redundant to add  a "strict" value, because we would only be behave "strictly"  according to an _undefined specification_.

This makes sense to me.
