In cleaning this one up, "umount -t nfs -a -l" left the socket there
still in CLOSE_WAIT. There were a few stuck "df" processes from our
monitoring script:

31370 D<   df -mPt nfs                 rpc_wait_bit_killable
31822 D<   df -mPt nfs                 rpc_wait_bit_killable
31847 D<   df -mPt nfs                 rpc_wait_bit_killable

...killing those made the socket actually close and change to TIME_WAIT,
allowing me to remount everything, and it all works again.
