I am trying to write some code that will determine whether an NFS
mounted partition is currently accessible.  The filesystem is hard
mounted and most file system will hang on a resource wait until such
time as the server is back up again.  As this is part of a larger
program I don't want this to occur.

I want to determine whether an access will hang prior to attempting
to access the file system in order to take some evasive action.

A short time out would be acceptable.  Can anyone suggest a system
call that will allow this.
