Time-outs are a real barrier, so leaving them out of the guidelines is
not a solution. If time-outs are needed for economic or security
reasons, the provider ought to provide a bypass - for example, by
letting disabled users register and get a "bypass timeouts" cookie.
So I'll try again:
2.4 Do not limit the time that a user may need to understand or
interact with your content.
* Provide disabled users with a way to bypass any demand to
respond within a preset period.
* Use automatic refresh and delayed redirection only when
necessary to bring superceded content up to date.
* Content must cooperate with user agent mechanisms for
preventing motion (including flicker, blinking, flashing,
self-scrolling etc) and for control of the rate at which
motion occurs. Note that flicker effects can cause
seizures in people with photoepilepsy.

Context matters. Seldom does *anything* have only one cause.
