Yes, Allegro blocks on any graphics routine under Windows when it is
switched out (if the switch mode requires it of course).

Even if the patch made Allegro send SWITCH_OUT events, these would only be
"fake" SWITCH_OUT events, i.e Allegro would never block and more generally
perform the tasks it performs for regular SWITCH_OUT events.

Hey! Shoud we really add a note on every feature that could be implied but
doesn't actually exist ? I thought the rule of the game was "Only rely upon
documented features".

That's precisely what I had in mind: allowing the user to set his "total
redraw" flag whenever the DirecDraw surface are lost.
