--- Comment #2 from Darren Tucker <dtucker at dtucker.net> ---
Additional data point: this only occurs when a pty is allocated.  (The
server here is OpenBSD current, but I don't think it's platform
specific).

$ ssh -o ObscureKeyStrokeTiming=yes server -X time xterm -e true
real    0m0.098s-p 2022 obsdsnap
user    0m0.010s
sys     0m0.040s


$ ssh -o ObscureKeyStrokeTiming=yes server -tt -X time xterm -e true
real    0m4.934s
user    0m0.000s
sys     0m0.040s
