Comment (by jelte):

 Not really about the snmp part, but I was wondering if we should make this
 a pull-protocol instead of a push one. I.E. instead of letting each module
 send their statistics at a regular interval, letting the main stats module
 request them at that interval. The result would be that modules would not
 have to take any action should stats module not run (and/or there is only
 one place where we need a timer for statistics, and we can make a command
 for stats module 'collect now'.

 One way to do this would be to let all modules automatically subscribe to
 some Stats channel on the msgq, and if a SendStats command appears, each
 one does what it currently does when it sends stats.
