This is already how ComplexProgressIndicator works. Your underlying 
code raises ProgressNotifications.

I think that it's reasonable to do this in a UI context (that is, if 
you start loading a file from the FileList in a Morphic environment, 
it's not wrong to use a Morph to signal progress).

Of course, the utility methods that get called to do the loading 
should not make any UI decisions or expect to interact.
