Sorry for the huge cc list. I will try to create a more focussed
list for numa policy user space in the future.

numactl-0.8 has been released. It consists of libnuma - which
is the prefered NUMA API to the NUMA policy system calls in the
Linux kernel -, numactl - a command line program for to 
run programs with a specific NUMA policy and various tools.

The biggest new features compared to 0.6 (0.7 was skipped) are lots
of bug fixes, PPC support and support for parsing numa distances
from sysfs.

It is backwards binary compatible to earlier libnuma releases. 

This version has everything I wanted to implement for numactl 1.0.
Unless some bad bugs come up it will be eventually renamed to

Please report all problems to ak@suse.de
