Yes - I believe that's right.  If a request is received for a slow 
object which is not in cache, and whilst that's being generated by the 
backend additional clients request the same object, then all requests 
are aggregated.

I think you'll need to look at the documentation around the 'grace' 
values to tune this to behave exactly as you want.
