In the early to mid '90s we built various heap-profiling tools to
examine the characteristics of heap data in lazy functional programs.
You can find papers describing this work by Googling "heap profiling".
You may be particularly interested in the investigation of "heap lag"
and "heap drag" -- see for example the ICFP'96 paper. Others have
worked on similar tools since, but I'm not sure how extensive heap
profiling facilities are in ghc, the most widely used implementation of
