Thanks. This is off to a very good start.

This needs to check and return NULL if malloc returns NULL.

Then, this should have added a copyright attribution to the top of the
file.

In fact, everyone that's contributing non-trivial amounts should be
adding copyright statements. I don't mind too much if people consider
their own contributions to be insignificant enough to not merit a
copyright claim, but when copying code written by others, we definitely
need to bring the copyright attribution along.

Would also be good to mention the glibc version and license in this
comment and in the commit message as well.
