I'm still stuck with the problem I mentioned in that thread. IMO, the UML
semantics are not clear in this area. Maybe you have a suggestion how this
should work?

- You'd probably want to go for post_event.
- Never ever call process_event() from inside an FSM!!! That function (like all
other member functions) is non-reentrant.
- fifo_scheduler<>::queue_event races with external events that are scheduled
by client code. In this context you almost never want that.
