As long as they persist while you have an open (or a delegation), it
shouldn't be so hard to implement, should it? If a filehandle expires,
then you throw away any cache associated with it, but as long as no
applications hold file descriptors for it, that's not a catastrophe.

But I'm a little confused whether rfc 3530's 4.2.3 gives a way for the
server to express that guarantee.
