[Haskell-cafe] SoC idea: interactive profiling

Hello all,

I entered a little proposal in the issue tracker:


As I see it, the graphical part could be a warm-up exercise with an
already useful product, and interaction with the rts would be the actual
challenge. Reasoning about laziness is far from trivial (at least I
often feel lost when trying to grok all the interaction within Reactive
;), and being able to browse profiler output on the spot is something I
felt the need for a few times already. Eventually, this could be a
contribution to an IDE project, even though it could as well remain a
standalone application for all the emacs/vi folk.

Profiling tools for parallel programs are in the make already, but I
haven't seen anything more convenient than hp2ps and little add hoc
solutions for analysing resource usage patterns. How do you all go about
