You might be able to get better help from other people with more nfs
expertise. My best guess is that "w" is somehow trying to interact
with the process accessing the stale nfs mount (at least "strace w"
shows it's accessing /proc/[pid]/stat), and since the process is
uninterruptible "w" has to wait (thus the appearance of "hang").
