sN PyZMQ Garbage Collector
Used for representing the reference held by libzmq during zero-copy sends.
This object holds a dictionary, keyed by Python id,
of the Python objects whose memory are currently in use by zeromq.
When zeromq is done with the memory, it sends a message on an inproc PUSH socket
containing the packed size_t (32 or 64-bit unsigned int),
which is the key in the dict.
When the PULL socket in the gc thread receives that message,
the reference is popped from the dict,
and any tracker events that should be signaled fire.
