+1.  I don't see what we're gaining by digging in our heels on this
one.  Retry loops around read() and write() are pretty routine, and I
wouldn't like to bet this is the only case where not having them could
cause an unnecessary failure.

Now, that having been said, I *really* think we could use some better
documentation on which mount options we believe to be safe, and not
just for NFS.  Right now we have practically nothing.
