Review Comment:
You mean to replace the whole search / match algorithm with find_next_bit /
find_next_zero_bit? I'd rather not do that, @yf13 can comment if that's
feasible.
I only noticed that finding a free granule takes longer the more the memory
is filled up.
The builtin ctz/clz have a time complexity of O(log(n))
