To answer this separately, procstat -kk of an exiting process
generating huge volumes of getattr requests produces nothing but the
headers:

# ps Haxlww | fgrep DNE
     0 21281 18549  1  20  0  11196  2560 piperd   S+     1
0:00.00 fgrep DNE
125428  9661     1  0  36 15      0    16 nfsreq   DNE+J   3-
3:22.54 job_exec
# proctstat -kk 9661
  PID    TID COMM                TDNAME              KSTACK

This happened while retesting on NFSv4.1.  Although I don't know if
the process was originally multithreaded, it appears it wasn't even
single-threaded by the time it got into this state.

Thanks!
