"When implementing the code for Tasks (as worker URLs within your app), it is important that you consider whether the task is idempotent. App Engine's Task Queue API is designed to only invoke a given task once, however it is possible in exceptional circumstances that a Task may execute multiple times (e.g. in the unlikely case of major system failure). Thus, your code must ensure that there are no harmful side-effects of repeated execution." -http://code.google.com/ appengine/docs/python/taskqueue/overview.html
According to this part of the documentation, it would seem that setting up an email-sending task-queue is impossible. After all, sending someone the same email thousands of times would be disastrous. Yet the documentation also gives email sending as an example use of the Task Queue. This seems to be contradictory. How can I create a Task Queue for sending email without running into problems of idempotence?
