Hi, Terry.

Ah, I see now.  I was thinking the timing for all authentication paths,
successful and failure, needed to be indistinguishable, but I see
now that that's not the case.  The successful path can be as fast as
possible, but all *failure* paths need to be indistinguishable so as to
avoid leaking.  Now I get it.  Sorry for being slow on this.  Thank you
for your continued explanation and patience.

For me, no.
