Nice tool. 

Some remarks. You can build high resolution timer support without the
extra lib package from the HRT sourceforge site. You need a recent glibc
and  some quirks in the source. See the cyclictest program I'm using.
http://www.tglx.de/projects/misc/cyclictest/cyclictest-v0.8.tar.bz2

It would also be cute to add tests for the PI support for
pthread_mutexes.
