There's one important point to be made: 0MQ currently behaves 100%
predictably in OOM condition -- it terminates the process. User is then
free to restart the process or take whatever emergency measures are
Any patches to OOM handling should preseve this 100% predictability.
zmq_send() can return ENOMEM instead of terminating the process,
however, it must do so consistently. Introducing undefined behaviour
under OOM conditions is not an option.
