Weaken and better document a stack analysis consideration

  * Rather than simply mentioning that something is a partial
workaround for an issue so old that it pre-dates our current bug
tracker, describe the constraint that is being maintained and the
why of it.

  * And then it turns out that the requirement of the constraint
is weaker than what was being maintained, so weaken the test to
match the actual requirements.
