Yes, warnings that "timer.start() is called asynchronously" are
exactly what I mean. You must call Timer.start from within a task.
If you are calling it from a command or event marked "async" (or from
an internal function called by one of those), then you need to post a
task that starts your timer, instead of starting the timer directly.
Search the mailing list archives for more information on task vs
asynchronous, task execution, and so on.
