Filed as bug  413450 with Debian.

I don't think I'll bother.  As the bug doesn't stop mountd from
working, but just causes it to soak up CPU time,  I'm going to decide
it isn't critical enough to warrant a gross hack, so my "official"
position is that glibc needs to be fixed.

Thanks for the bug report.
