Re: nfs client performance while server is down

[Whoop Whouzer <tiredandnumb@gmail.com>]

I am not stating this is an NFS problem at all. I am not asking anybody to fix
anything.
I asked if this issue was by design. I was told it wasn't (as nfs is stateless).
So, therefore I considered it as a bug (which I don't believe to
reside in either nfs or nautilus). I am just trying to figure out
where the problem lies.

I am not talking about implementing "disconnected NFS" mode,
synchronisation or anything like that. There is not something missing,
there is something not working properly, somewhere, and I'm trying to
find out where..
