This report was induced mainly by the following message being the thing:
> Something unseen opens the door. Your meditation is interrupted.
You don't stop passwalling when you receive damage but you do when a nearby door is opened - very odd. But there are other cases that seem odd to Me:
* You stop passwalling when you become constricted (however, you can passwall while *being* constricted).
* You don't stop when you're blinked - distortion, dispersal trap, etc. (Teleportation does stop you. Being trampled, too.)
* You don't stop if you're paralyzed in the process - you continue channeling at the moment you're able to move. Same with confusion. (I don't know about getting zero stats.)
* You don't stop if the wall you're passwalling through is completely (partially could be considered ok) dug out.
If I remember other cases I'll add them later.
