hm… recovering from heap allocation failure, that I can see, but if you
can't allocate on the stack, I don't see how you'd recover. When that
happens, you've already crossed the line to hell, and all you can do is
exit fast.

well, if you declare it with a variable available in the same context,
then shouldn't need to `sizeof()` that array, you already got the size
available as that variable!

yup, that I did not really understand…
