specifically, i'm trying to have a scheduled job queue seed 1-50 'tasks' at once, each one using a seperate DB connection and running in a seperate thread. once they all complete, the job reschedules itself to run in the future.

I suggest you take a look at the asynchronous task queue on which my sAsync package is based. I've been lobbying to get it included into the twisted code base, see http://twistedmatrix.com/trac/ticket/1768. The latest SVN of the module is at http://foss.eepatents.com/sAsync/browser/trunk/sasync/taskqueue.py and the API document is at http://foss.eepatents.com/api/sasync/sasync.taskqueue.html. Unlike the rest of sAsync, which is GPL'd, the taskqueue module and its unit test module are distributed under a variant of the MIT license in order to be suitable for inclusion in the Twisted codebase. Best regards, Ed
