Hm.  I wonder whether it would be all right to just skip files for which
we get EPERM on open().  The argument being that if we can't write to the
file, we should not be held responsible for fsync'ing it either.  But
I'm not sure whether EPERM would be the only relevant errno, or whether
there are cases where this would mask real problems.
