The problem  is, you got to have an event_timer in your loop otherwise you
will never be able to change the values.
If there is no timed event, why should you specify it, and the gem-dispatcher
is doing more, than he must do.

Since this 'feature' exists since tos 1.0, it needs a simple "we will keep it"
from Atari to avoid 'workarounds' like yours.
If, on the other side, atari sais "this is subject of change" we have to use
this, or any other solution.
But I doubt, there is any solution, that is as elegant as 
the above.
