At some point, are we going to want to remove libc_r as part of the
upgrade process?  (I'm assuming that's going to force recompilation of
many 3rd-party apps).  I can imagine it can make troubleshooting more
difficult if we're going to have some people with libc_r and libthread_xu
and it won't have been a conscious decision in either case.
