Normal NFS client reaction when connection lost then re-established

Say I have an NFS share mounted with defaults. There is no outstanding IO to the share and the server goes down. The server comes back up and there is an attempt to access the share. What should happen when this attempt is made? It seems to me that it should be like the server never went down. Instead, things behave more like the server never came back up: any application attempting to access it hangs indefinitely.

Using the mount option 'soft' prevents this from happening, but it doesn't seem like one should have to risk 'silent data corruption' to prevent the client from going completely stupid when it loses contact for a period that no contact should be necessary.
