My guess is that part of it is the back scale (the string behind the bridge), with tension creeping over the bridge. And part of it is whatever it is that causes adjacent strings to go way out of tune when a string breaks. I don't have experience with this, but my guess is that some good forearm slams after the first pass, or alternately some vigorous string stretching techniques might stabilize it faster. String stretching meaning deflecting the string with a dowel or a brass tool with a groove, pressing on each string pretty strongly. These things seem to help with a piano that hasn't been played for a long time, so they might work with what you are talking about as well.
