[issue6594] json C serializer performance tied to structure depth on some systems

Nope, all three json's implementation do not release the memory. I used 
your patched one, the one shipped with 2.6 and cjson. The one which comes 
with 2.6, reach 2GB, then release 200MB and stays with 1.8GB during 
sleep. The cjson reaches 1.5GB mark and stays there. But all three 
release another 100-200MB just before the exit (one top cycle before 
process disappear). I used sleep of 20 seconds, so I'm pretty sure memory 
was not released during that time, since I watched the process with idle 
CPU.
