Hi John,

Changes in v2:
I moved the wrapper around numa_sched_setaffinity
to lib/rt-numa.c and added the pid as a parameter.
I called it try_numa_sched_setaffinity since it's basically
just a wrapper, that warns if an error occurs.
I'm not sure if this is what you had in mind, when you
suggested moving that section to rt-numa.c
The code-style should also be consistent now.


This patch adds the option --mainaffinity to specify the affinity of
the main pid. 
This is mainly useful if you want to bind the main thread to a 
different (e.g. housekeeping ) CPU than the measurement threads.

Regards

Jonathan
