It doesn't help at all with your problem - but I thought I'd point out
there are other ways to exploit multicore machines than using threaded
ATLAS (if that is your goal).

For example, I use single threaded libraries and control parallel
execution myself using multiprocessing module (this is easier for
simple batch jobs, but might not be appropriate for your case).

There is some information about this on the wiki:
