Just a subtle point, but the boost::timer class returns CPU time used
not elapsed wall-clock time and would return results of ~0.0 for a
function that just sleep'd for a second or two.

If what you're looking for is a high-resolution clock, try
<boost/date_time/microsec_time_clock.hpp> (at least in the latest
CVS).  If you want performance or profiling information, use
boost::timer.
