Thanks.

The manual page seems promising, talking about microseconds, but I don't
believe it actually has a microsecond resolution. I think it has the
same jiffy resolution that times() has. Do you believe that it does
have microsecond resolution?

I think we're starting to build here a long list of manual-page bugs...
