I don't see any problem with it, although I don't know if it's necessary. The wikis have always had a timeout like this, and I am unaware of any complaints except for this one, and only because the timeout was set to such a low value. However, I'm willing to concede that we have some very dedicated editors who may take more than 4 hours on an article :)
