On the second point, I would be interested in hearing what you 
find out. In general, I have not had any luck with speeding 
things up inside loops using manual memory management. The only 
that's worked is avoiding allocations and reusing already 
allocated memory.

You're splitting things into GC-allocated memory and manually 
managed memory. There's also SafeRefCounted, which handles the 
malloc and free for you.
