This update is really great! Now we can see 'Mean' users awaiting for 
their requests to be served - this information is very useful, because 
we now can calculate avarage wait time for each request.

For example we know that an average request time is 0.15 sec, than if 
our mean queue is 32 requests, each request will be served in 
(32+1)*0.15=4.95 seconds. This information is very useful and even 
NewRelics cannot provide it.

I'm going to build graphs for this data. You can see live stats for 700k 
request per day project running on 2x Xeon E5410 2.33 Ghz (4 cores each):
