For the record, I also see similar problems on my machine, which is a bog
standard 6 core Phenom II. However I simply have a widget on my desktop
that I swap through the various CPU frequency scaling governors, namely
going to performance when I need to do heavier audio work. The rest of the
time I keep it on low power and can do basic audio work till I max out the
single core I am working on in A2 or Mixbus. Jack doesn't stop running on
my machine really.

Personally I like my setup, it is a piece of cake to click on my desktop,
and select the appropriate governor when I need to do work. And I have
never had a problem on max performance with xruns on any project really
till I max out the CPU with processing of course.
