He said 0.5 is too long, I tried 0.1, and find it too short to be noticed, 
so I tried 0.25, which seems okay from my point of view.

It's just a quick proof of concept, perhaps it's possible to do something 
better, I'll try to do that if there's an agreement that it's a good 
starting point.  That being said, I'd be surprised if you can move your 
eye from point to the echo area in less than 0.25 seconds.  What you 
describe is annoying only if you already look at the echo area to see the 
error.

FWIW, I'm not sure it's right to do that, it might interfere with packages 
which use the mode-line in exotic ways.  Moreover what's the point of 
changing the color of the mode-line?  It's distracting, what the user 
should be invited to look at at that moment is the echo area, where the 
error message is (about to be) displayed.
