[Eric D. Tarkington] Your question does raise a good point, though. It is possible to launch multiple threads of control that will come back asynchronously to a single activity. Offhand, I can't think of a situation where I would want to work this way, but it doesn't defy any laws of physics.
[wmj] People in a team are 'performing' "multiple threads of control". One or more per person and/or role.

(Please don't lose any sleep over the W/E, answer can wait until Monday.) I don't think the definition of an activity allows your hypothesis. The activity diagram is a specialized form of state diagram, and any given activity or state operates only in discrete ticks. An activity is a degenerate state, with no memory of the past, and its response to an event in a particular tick is atomic. Your question does raise a good point, though. It is possible to launch multiple threads of control that will come back asynchronously to a single activity.
