Please try 1.1.x.  There is one known problem in 1.0.x which 
causes it to allocate about 2 pointers per buffer sent.  This is 
known to be noticeable in long-running response case.

The problem was fixed in 1.1.4, but unfortunately it's impossible 
to merge the fix into 1.0.x due to required API change.
