We do actually have a Jobs system implementation in place for Bugs now (see lp.bugs.interfaces.bugjob and lp.bugs.interfaces.bugheat), though I don't know how much use it would be in this instance. Adding new Job types is a fairly painless procedure, but I guess that in this case there's still a lot of work that would need to go into moving from our current system into the new one. Subscribers have caused us quite a lot of problems for a while, by the way, so you're not the first person to be knobbled by this kind of timeout. -- Graham Binns | PGP Key: EC66FA7D _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
