This is something I never paid much attention to before, but isn't the backmost part of the corridor set on Deep Space Nine merely a huge photo creating the illusion of a longer corridor? You never see anyone coming from there and whenever people run towards it (like O'Brien in Whispers) they jump to the site in the last possible moment (see the second image below). Another hint is that the photo of the fake corridor always stays the same (compare the two images). The pattern of the lights on the floor and ceiling also doesn't really match the pattern on the real set.
So, did anyone else notice this? And – more importantly – does anyone have any background information on this? How long is the actual corridor? Is there an image of the photo wall?
