I'm looking forward to the answer to this question!

There are applications that could benefit from running several threads, 
yet not to accomplish the vector/matrix operations using blas. I thought
about working on this and have picked up several important comments from
this discussion. I have wondered, for example, if there is an option that 
a user can set to limit the number of threads (package multicore uses
an option to set the number of cores). It seems that we need to agree
on a few basic rules. If there are some already outlined, I would like 
to have a reference to them. If not, perhaps there is an 
on-going discussion on the topic someone could point me to.
