Thinking off the top of my head, you could make a histogram call to
the selection "channel" at 255 (fully selected) and see if the
returned pixel count equals the number of pixels (width x height).

Assume I have a selection on small area (for instance a 20px circle),
and I invert it. Now, if I grow the selection by a sufficient amount
(10px in this case), everything gets selected.
Is there a practical, fast way, to detect this case, i.e, that the
selection covers the whole layer (or ima
