I believe Bryan is referring to the problems that you can now see in the 
system using DTrace.  There isn't a specific list of problems.  In 
nearly any given area, one could find room for improvement.

Another instrumentation tool which gives you the same data doesn't help 
fix these issues.  Pointing DTrace at other parts of the system to get 
data on the cause can help one find solutions to these age-old problems.
