Wouldn't surprise me one bit. Over the years I have had a number of NFS
or VFS problems reported as "autofs bugs", mostly because it makes
mount/umount a significantly more common operation. It also makes it
possible for a filesystem to get called for expiry and by the time the
daemon calls umount it is no longer unmountable. This means the code in
the kernel to reject busy umounts has to work. This has been the
problem on several occations.
