That's not quite true: 100ms might be the limit of human reaction to 
unanticipated events, but if you're doing something repeatedly, the 
delays become easier to notice.

I don't know about 10ms exactly, but 20-30ms - definitely. It will annoy 
some people more than others, but it creates subconscious impression 
either way. We have just recently fixes a related bug in Company 
(regarding increased visual latencies), with multiple reporters and 
benchmarks.
