This is only true for stuff that costs more per unit realtime, but the
simplest solution is to clamp realtime.  We clamp realtime to 100ms to
avoid these problems in our games.  So you still get the progressive
poor performance, but it hits a floor really quickly and then recovers.
The artifact is, of course, that real time slows down in the game, but
this is preferable to having your framerate drop even lower.
