`LinearAlgebra.BLAS.set_num_threads()` sets the number of threads. But, how to _ **get** _ the number of threads (so that I could save it, set another one, then restore the value)? Thanks.

I think you can use `get_num_threads` that is defined here:

thanks. Should I assume that this function would be available soon in future releases?

In future releases hopefully BLAS will just use Julia’s own threads.

Someone can make a PR for having this in the release.
