> I have observed a fairly substantial memory leak using the blocking classes 
> in proton.utils.  Mainly with sending messages.  
> Observations:
> {code}
> growth =  52 MB  for  10,000 messages sent
> growth = 104 MB  for  20,000 messages sent
> leak   =  52 MB  per  10,000 sends or ~5 kB / send
> {code}
> The attached reproducer, can be used to collect and display statistics.  
> There is likely a better method for measuring the memory growth  but this was 
> easy.  Perhaps there is something incorrect/missing with the way I'm using 
> proton or measuring the memory growth/leak?
> {code}
