annotate mod_measure_memory/mod_measure_memory.lua @ 4980:da151f9af861

replaced 'session' with 'origin' in push_disable session is not defined in this function, trying to access it leads to an error. The correct reference seems to be 'origin'. (This may have come about by copying from the similar code in process_stanza_queue.)
