Yes, this is what I ended up doing before I saw your other reply.

To be honest I don't know enough about C to know the performance of 
bytevector->pointer, so I was assuming Chickadee's approach was done for 
a reason. But if you think it's not a big deal then I'm happy to 
simplify things! I think I will remove this caching for now.

Thanks for your help, and Arne as well for digging into the issue.

Best,

Walter
