yep, sounds great to me :-)
although with some hacks one can already have a poor mans real time
interface for heap profiling:

I agree that the effect of laziness can be very hard to grasp, sometimes it
even feels that I traded the annoying side effects from imperative
programming to "lazy effects" in functional programming... Can't seem to
have my cake and lazily eat it :-)

Hello all,
I entered a little proposal in the issue tracker:
http://hackage.haskell.org/trac/summer-of-code/ticket/1570
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 profiling?
