I agree completely.
Though I also agree with Szabolcs.
We want to maximize backwards compatibility where possible, in this case
getting 4KiB back from the stack guard accounting is enough to allow your
test to pass. This is good and will help ntpd binaries to continue to run.
We also need to be clear in our documentation on what can and can't be
done with PTHREAD_STACK_MIN. I *do* want to add text into the manual that
explains what can and can't be done with the minimal stack.
