There is probably room for optimization in glibc if you know what locale you
are using. There is a global locale object and several other locks that are
taken when changing locales. Rather than change IFUNCs you could do something
else to handle the locales differently and accelerate these operations.
So rather than RESOLVED/INVALID, this is probably just an RFE.
