This hasn't been a problem to date.  As a practical matter, I think the
xmalloc/xrealloc interfaces appear in enough Gnu software to have well-
known interfaces.

As I said, I want other Gnu software (e.g., bash) to be able to override
the readline definitions of xmalloc and xrealloc and have all their
`application-space' (non-libc) memory allocation go through a single
