My prayers have been answered and the abominable red barriers in Monastery of the Scorpion are gone!
Happy Stealthing!
EDIT: Even better. They go up when you aggro stuff! (Silly Fighter!)
EDIT2: Got a Yellow Alert at one point and when I got to Sannyasi he made a beeline straight for me (even though I was super stealthy). Might have been a fluke, but not sure. Perhaps if you hit a certain alert level, he's on to you no matter what- which kind of makes sense to me. (On a side note, I was still able to dance around and get it solved, but it wasn't easy).
