As the person who went through libc and added most of the weak
symbols in order to satisfy the needs of the threads library
and to separate libc_r from libc, I would kindly suggest that
you leave things alone.  But if want to change things, please
make sure they work with all the threads libraries that we
currently have.  I don't want the burden of doing this nor
have it impact our current efforts.
