Well first you need to find all files, that need to be considered. That
takes some time. And its far too easy to change the mtime, especially when
using an uninstalled ptxdist, so you need a hash. I tied to do something
like that and gave up when I got +10 seconds to get a 'everything is up to
date' for a larger BSP.
