Results in much more reliable soft recovery on
Steam Deck.
Waiting 500ms for a locked up shader is way to long I think. We could
increase the 10ms to something like 20ms, but I really wouldn't go much
over that.
This here just kills shaders which are in an endless loop, when that
takes longer than 10-20ms we really have a hardware problem which needs
a full reset to resolve.

Christian.
