Re: [boost] High resolution time routines

I agree that a high resolution timer is needed. One quick way to provide
this is just to use the various high resolution timers that already
exist... wrapping them with a common interface. And the best part is that
someone's already done this (in C). The Interval Performance Monitoring
(IPM) package does this. It is part of the PHiPAC high-speed matrix
multiplication package. IPM is portable to most unix's. Boostifying this
package could be a good place to start.

I've uploaded ipm-2.0.tar.gz to Files if anyone is interested.

Cheers,
Jeremy
