Setting aside the specific code details, I would suggest that you not
review the glibc code but rather review the glibc documentation and the
susv3/posix specifications.  That way, if it behaves according to the
spec but breaks glibc you can push for a patch to glibc.

If it happens to work with current glibc but is not standards-compliant,
then it could break in the future.
