from nfs(5):

       soft           If an NFS file operation has a major timeout then report
                      an I/O error to the calling program.  The default is  to
                      continue retrying NFS file operations indefinitely.

So this seems to be a case of "feature, not bug". It'd be great if you
could test this with a soft-mount too.
