Hey Greg, thanks for the info! I see the variable
set in my 8.4.7
release here, but I think MATLAB must have been doing
that didn't refer to it. What I was seeing was not
but rather pthread-related, it seemed.
I'll see if I can enlist one of the team over there
take a closer look
at it to confirm. At the very least the variable would
provide a good
way to make a maxNumCompThreads() call.
