Add timer and timeout scaling library

Heavyweight tools like drmemtrace slow down an application considerably, by up to 30x-50x or worse (i/o bound for drmemtrace). Yet large applications often have timers and timeouts operating in regular time, resulting in timer signals with a much higher frequency relative to code, as well as sleeps and timeouts expiring much earlier than they would have relative to other code.

This is a feature request to provide a library or part of an existing extension to modify timer and timeout parameters to the kernel to be scaled to better match the speed of the rest of the application.
