auto_reconnect not working

[rosslagerwall]

A basic synchronous program which does nfs_stat(); sleep(800); nfs_stat(); hangs in the second nfs_stat call.

It would appear that the auto reconnect is not doing it'sjob and so it calls poll on a file descriptor that is -1 which than makes poll wait indefinitely.

Thanks for looking into this.
