It seems we really need a wrapper for time().
I absolutely concur. Something like this (most of it is blatantly copied
from Marius' patch)?
Well, I don't think it'll make a difference. The tiny test program below
prints twice the same number. My analysis of the time() implementation is
obviously flawed.
