Yes. Fundamentally untenable.

Not allowing stack faults has been a wonderful simplification. It's one
of those things that just plain makes the kernel easier to maintain.
Saving low single digits of system memory is not exactly making me eager
to go back to the harder-to-maintain days.

I seriously doubt that this 1% is the lowest hanging fruit for memory
bloat on these systems. ;)
