The case that triggered this was somebody thinking
-m took a byte count, so very likely that an error message
saying "you tried to allocate 38TB" would have made their
mistake clear in a way that just "allocation failed" did not.
It also means that if a future user asks us for help then
we can look at the error message and immediately tell them
the problem, rather than going "hmm, what are all the possible
ways that allocation might have failed" and going off down
rabbitholes like VM overcommit settings...
