Indeed, so why are you complaining to us?

I'm fairly unenthused about a kluge that hurts performance on
standard-conforming systems (by forcing them to traverse the slow code
path) in order to cater to a long-obsolete glibc whose behavior conforms
to neither the C standard nor its own documentation. If this bug is a
problem for you, update glibc.
