Responding to both Dag and David,
 
OpenMP is pretty widespread in supercomputing, and so is OpenMP +
multiple threads using LAPACK at the same time. This does NOT sound like
any issue with multiprocessing to me.

These are built on dynamic thread-level (pthreads), not process-level (multiprocessing) parallelism.  My original statement stands.

| accelerate, just to go away from it for our binary releases.

Oops, I missed that last part of your first email.  If this is a problem for people, I agree that the binaries should avoid Accelerate.
