Thinking about this a bit more this morning on the shuttle, there's a
strong argument that this is a glibc bug, and that the stat() approach
is a correct fix, if not necessarily the most ideal one.  That
argument is simply that glibc is caching data without a mechanism for
invalidation; and a cache without invalidation is always a bug.
