thanks to Michael for setting this up!

The rt-preempt-integration branch is now ready for use.  The latest
patch set from John Morris has been applied, and the code is ready to
check out and use.  If you are using Debian Wheezy, make sure you use
gcc 4.6 instead of 4.7!

While the code is usable as-is, at least two areas need some attention:

* Modification of the debian/ directory to enable building preempt-rt
packages allowing easy testing on modern Debian/Ubuntu systems that
ship with the preempt-rt kernel as an option.

* Review of permissions and the setuid bits required to run.  At the
moment if HAL ever crashes or doesn't load properly, it is fairly ugly
trying to get things cleaned up so you can run LinuxCNC again.

NOTE:
If you would like to experiment but do not have a preempt-rt kernel, I
believe you should be able to build and run as-is, you will just
experience nasty latency values until you run under a preempt-rt kernel.
