a collegue pointed me to this post about a high resolution time
patch for the 2.6.5 kernel. i'm not 100% if it has been mentioned
here before, nor of how much interest it is, but just in case.

Thanks for the pointer. It's certainly of interest.
Has there been any discussion of including this in the mainstream
kernel? It would be wonderful to finally have full POSIX nanosleep()
and clock_nanosleep() support for everyone.

linus nixed it at the 2.5 stage. the POSIX API was added to the
kernel, but not the APIC-based high-res implementation. he just didn't
like the way it messed with the "tick".
jesse chappell has played with a previous version of the patch and has
had problems with X stalling for seconds (?) when in use. the
resolution also didn't seem anywhere close to what was claimed.
