Alfred,
If the operation times out because the server rebooted (or because
of a network glitch), rather than losing data, the client can
potentially have the data written out successfully later.

Alfred,
FYI - I am working on changes that would retain and re-dirty the
buffers on other NFS errors as well. For example, on an ESTALE,
there's little point in retaining the buffers. But on reception
of an ENOSPC, it might be worth retaining and re-dirtying the
buffers, as space could free up

Hi Gleb,
