IMO this is the key factor in deciding how much compromise is too
much: the compromise being between, on the one hand, a
real-time-updated thumbnail of activity if it's currently running; on
the other hand, no thumbnail it all.  The factors each solution would
be judged by include performance, decrease (from the ideal) in
usefulness, activity code / API complexity.

The two competing compromises, that lie just astride some key boundary
in the solution space, seem to me to be:

1) saving (the thumbnail preview, but also I imagine the actual
application state as well) just often enough that the user will never
be surprised that, when resuming, the state isn't as they last left
it; and
2) saving only as often as the user explicity asks to save (and at
application shutdown, if possible - currently, this means the app has
to be visible)

Your patch does #2, I believe.

FWIW, I think that the features being sacrificed are not used often enough
to justify the loss in performance.
