Do note that async mode, due to how it works, *does* open a possibility
of data loss - on a write, the remote NFS server can say "done" immediately,
but then crash before committing the write to disk.

However, being stuck in 'D' state means the remote server didn't reply
at all, so that won't help much, especially for already-hung processes.

Also:  In this case, 'cat /proc/mounts' is your friend - using 'df' to see what's
mounted will almost certainly also hang.
