I figured out later that this isn't always true -- for instance, in one case
root could ls a directory, but others couldn't (and new mounts wouldn't
work).

Here we go. The dump is a complete tcpdump from the server (129.241.93.19) at
the same time as a client (129.241.93.50) attempts to do a "mount -t nfs4 -o
sec=krb5i cassarossa:/itk /mnt". The call traces is the result of a "cat
/proc/kmsg" while running "echo t > /proc/sysrq-trigger".
