There are always problems.  You can always come up with something that
will crash in 4k, IMHO.

Rather than foisting this upon everyone, I'd rather see work put into
making stack size a boot parameter or something, so that people can
choose what's appropriate for their workload (or their IO stack, if you
prefer).
