A busy multi-image house that I worked at used those on all the darkrooms. If the door was turned away from you, the procedure was to smack the door a couple of times with your open palm as a warning and whip the door around practically in the same motion. If someone was half in the other side of the door, they knew they'd better jump in or out fast or they would become a door stop. Surprisingly, this actually worked pretty smoothly even with lots of people working frantically on different projects.

When I was in the Navy, the print rooms I used on shore tended to have these doors, but the one onboard ship had a 3-door vestibule. (Hrm.. come to think of it, I think only the b&w printroom had a vestibule. The color printroom had a spinning door, I think)
My favorite story about these doors isn't really fit for direct transcription into apug, but when I went to a photo school in Key West, FL, we'd come back from lunch and, uh, editorialize as we were, uh, passing through the door and quickly close it back halfway to surprise the poor schmuck who came in next. (*smirk*)
Good point about 16x20s or larger mounted prints, not to mention large boxes of paper. Maybe I'll have to separate the structure into finishing and processing/printing areas so I mount outside the the darkroom and/or build some sort of a passthrough into the wall.
I anticipate this being just invaluable when I want to pop out of the darkroom for something during printing sessions or especially during lengthy DBI sessions.
