broker

   > Can you also please record the impact on heap size in the broker? We 
already have pretty massive broker heaps and putting more pressure on them 
would be problematic.
   
   This is used memory comparison on our test broker over a day, grey line is 
without this patch and blue line is with this patch. There is slightly higher 
memory usage with current published segments cache on broker.
