Title: When using eventlet I have noticed a sizeable memory leak, this patch fixes it

accept_callback on a task was trying to json serialize task info which was raising a TypeError (because instead of having a pid it was receiving a greenlet instance which can't be json serialized) and that was leaking the whole greenlet on every processed task.

This was happening with eventlet 0.9.16
