I don't think it's inherently that... it could be in some cases, but not
in others.  In either case, an allocation failure should be handled in
the calling layer... or we have a much more serious problem.

However, I suspect the most common case where we'll hit this is when
something wants to fit inside a chunk where it simply doesn't fit ...
and it'll either move on to the next plausible chunk or fail at that point.
