Summary

Emit statistics / visualizations of heap fragmentation. There are edge cases where we can't currently consolidate adjacent free cells into a larger, contiguous free cell. This would let us empirically answer whether that is a problem in practice.

Motivation

Remove "unknown unknowns". Be a better allocator.

Details

  • Maybe use graphviz.

  • At least get some statistics / aggregated numbers on free vs allocated and distribution of free cell sizes in the free list.
