Yes, it's not a problem for the Cython work.
The main issue at the moment is that I've had significantly
less time than usual over the last two weeks to work on it.
Hopefully this week will be a little calmer and I'll be able
to do a little more.

On the other hand, though I have no experience working
with accelerate, this does still sound like a really good idea.
Thanks!
