That turned out to be a critical factor.  When I eliminated the 1-second
sleep in clogin before sending the password, multiple s/key logins on the
same account got more reliable.  Without using the "-p NN" option to "par"
to sleep between forks, some of the six routers I was testing with were
missed in rounds 1 and 2, but all were caught by round 3.  All six
completed in round 1 when I told "par" to sleep two seconds between forks
("-p 2").

So my patches to clogin for OTP will skip that 1-second sleep before sending
a password if OTP is in use.
