AFAIR proc_exit walks down a list or two. Depending on how much is going on, this may take a while. Looks like my DTrace probes and scripts offer the opportunity to do some performance related observations in an easy way. Now we just need some interested souls to actually do it and optimize some things. It would also be great if someone could have a look at http://dtrace.org/blogs/brendan/ and code up some nice GUI respectively an observation and analysis tool. Graphs as represented by Brendan give a much better way of understanding what's going on than a lot of numbers.
