So a stronger hint than "the script is still running?"

I would be more interested (from an implementor point of view) in a 
block that said "inside this block, no need to do layout even if I ask 
for layout information".  That would provide me with information I don't 
actually have and allow me to optimize better.  However, I think it 
would be very difficult to use for authors, because it would be too 
error-prone...
