Jones, Simon Marlow and I have been working on infrastructure for logging
run-time events and a graphical viewer program called ThreadScope. Hopefully
these features will make it into the next release of GHC. We hope the event-log
viewer ThreadScope will be useful for the performance tuning of parallel and
concurrent Haskell programs. You can see a few screen shots at the program's
website <a href="http://raintown.org/threadscope">http://raintown.org/threadscope</a><o:p></o:p></span></p>

<p style='line-height:14.25pt'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>Before
making the release I thought it would be an idea to ask people what other
features people would find useful or performance tuning. So if you have any
suggestions please do let us know!<o:p></o:p></span></p>
