i am preparing a demonstration on memory management/garbage collection,
and to give the students some real life examples,
i am looking for a simple patch to some Haskell runtime system
so that it would display the heap *while* the program is running.
like, opening an X window and mapping heap cell types to pixel colours.
(i'm prepared to accept horrible slowdowns in program execution)
i quickly hacked such a display into hugs, just using 3 colours
(cell is in free list, cell is reachable, cell is unreachable),
but i'd like to have this for some other (e. g. generational)
collector as well. any hints appreciated.
