I'm not sure how useful this is. When it comes to measuring where the 
time goes, the cumulative tree of multiple processes shows you if you 
have deficiencies in the core framework handling. This is extremely 
useful. And it breaks down quite nicely into separate pieces where 
actual different work is involved. I don't think you would get much more 
useful information if you were to break things apart. And I can say for 
sure that for the purposes of our server profiling it would be pretty 
much useless - under load we run literally hundreds of processes.
