Thanks.

My unit tests (and many other people's) are functions which throw exceptions 
on failure. By combining profiling and checking for exceptions, I can both 
time my test-case and assure its success. However, this is no longer an 
issue because you will be already including timing in the next version.

What is the status of this version?

Would you consider submitting these as a separate high_res_timer 
mini-library for boost so that everyone can have easy access to them? It 
seems to me that these would be good additions to the Boost.Timer library?

If you haven't already, please take a look at 
http://www.cdiggins.com/profiler/ , hopefully this explains my goals. If you 
have specific questions I will do my best to answer them.
