Propagated to where? There really is no possibility of
propagation (you certainly do not want to introduce asynchronous
exceptions for this purpose!)

I would have preferred that an unhandled exception in a task
caused termination of the entire program, you can always get
the bizarre effect in the RM if you really want it by doing:

      exception when others => null;

at the outer level of a task

Check your compiler, it may have an option for handling this
error situation nicely. But in general, yes, that's a good idea
(mandatory when others at the top level of a task).
