Are you sure this applies to older glibc versions as well? When
behavior of a glibc function has changed in time, usually (or I should
probably rephrase this as "in the most fortunate cases..." :), but
let's not be that pessimistic ) the man page specifies that; if it's
the case here, it might be good to say: "mmap is used since glibc x.y,
malloc was used before".

Thanks,
Stefan.
