Just a minor point which may be of interest: Many operating systems
(including Linux by default) overcommit memory, so there is in fact no
guarantee that memory returned by malloc() will in fact be usable under
memory pressure.

So, getting a non-NULL pointer from malloc() is not a guarantee.

(There are good reasons for this behavior.)
