OK, I issused fstrace setset, then fstrace lsset:
Available sets:
cmlongterm active
cm active

Then I waited for the token to be lost, then I fstrace dump.  But the
word 'token' does not appear in the output.  I tried fstrace dump,
fstrace dump cm, and fstrace dump cmlongterm.  Did I do this correctly?
