In lib/31112 I described how some programs, including apparently some
system programs, are written to handle running out of memory cleanly
(running a garbage collector, reducing cache, whatever), and may even
expect to run out of memory in normal operation.  Because of these
programs, 'A' is inappropriate for a system-wide malloc option a la

However, an option like 'A' that does not consider running out of
memory to be an error would probably be just fine for system-wide use.

        pick a new letter, add a new flag in malloc.c, etc
