I'm obviously on crack. :)
That last line is of course totally wrong and shouldn't have been there.

So what we really end up with is this, right? 22 * ((realusecs >> 20) + 1) /21
That's promising, except that the numerator won't fit in 32 bits (22 times some time_t will be too large), so we'll be stuck doing a 64-bit division again.
However, if we can find an alternate approximation that works with 32-bit math, that might solve the problem.
