We have some new tools coming, perhaps for GHC 6.8. Michael Adams has ported
the GramSim parallel performance-analysis tools to GHC, so we can generate
graphs of runnable/running/blocked threads over time, amongst other things.
This should make it much easier to get a handle on parallel performance, which I
think is the area that we're most lacking at the moment. I'll try to get the
patches in as soon as possible.
