TLSF has nice properties (O(1) malloc() and free()), but it uses ~3.5kB for "free lists". I don't think we can afford that. There's room for optimization for our low-end devices in the implementation (allowing higher internal fragmentation, limit max allocation size to something practical like 2**16 or less, use pointer compression), but that needs work.
