Maybe you'll become a "c type" anyways  :)
I never set out to be, either, or even any sort of developer;
just kept editing+retrying until stuff stopped breaking.

Thanks, I made r59003 based on that info.

Your original message was around 15ms, so that is definitely
inline with what's documented, there.

Please let us know if it still fails again.  Thanks.

And yeah, maybe you can figure out a way to improve
Process.times for other Windows users.
