These functions are still mostly implemented in asm, so I'm not 
sure there is an "idiomatic D" way. I would only wrap them into a 
function working with slices and checking the length. Mike?

As said my allocator is nothing official but I would be overhappy 
if someone finds it useful. I can also advice to look at Doug Lea 
malloc:

It is like a book. It's one of the best documented programs I've 
ever seen.
