I have 3Gb of memory and hibernating takes a year and a day, much longer
than it would take to shut down, reboot, and open all my applications
again, so until hibernation to a compressed image becomes available
(would it not be possible for instance to zero the unused memory and
then pipe the used and unused memory contents through a compressor?), it
isn't an option unfortunately.

As far as I can remember, I have hyperthreading enabled in the bios, but
it doesn't seem to be giving me any problems.

So basically, as I said before, apart from the hibernate issue, which
can be worked around easily, the latest rt kernel seems to be working
like a charm. The main challenge now, will be to make jack2 survive
through a suspend-resume cycle, which is something I never managed to do
in the past.
