I have handlers like these also. I have multiple work-arounds. You can
use suspend and resume to preserve the defaultStack and restore it. Lots
of way to work-around. I am curious if others have seen this and whether
anyone ever found a reproducible recipe.

So you have seen this behavior? In what versions of LC? Did you ever
find a consistent recipe to reproduce it?
