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.
