I disagree.  Even if the new stack-overflow code works, it doesn't
change the fact that a stack-overflow is a problem for the end-user and
we should try to avoid causing such things.

IOW, Dmitry's overflow-handling is good because it makes the failure
a bit cleaner, but it's still a failure that we should strive to avoid.
