In all cases it is useful to have some sort of "tasklet manager" that helps keep track of tasklets. This can be as simple as a set of weakrefs to tasklets that you create, or something more complex, like a tasklet manager that creates tasklets for you and assigns them to different sessions, or contexts, or whatnot.
More complex application can benefit from tasklet watchers, At CCP we would for example be able to enumerate tasklet by some arbitrary context, and "cancel" them. We would have "cancel" barriers, for example, across service call layers. This would enable us to cancel all executions that were being done on behalf of some session that was changing state, for example.
