Just as an FYI, most of these are theoretically eliminated or at least drastically mitigated by a switch from mutable state to immutable, purely-functional data structures. The cost of course being somewhat increased memory consumption and a bit more slowness (or a lot, depending on the algorithm).

If you ever get a chance to work with the BEAM VM, it's pretty tight.
