Here is what happened when I tested with the '-r' option:

Initially...

root at 4871a0e3589e:/# ps auxf
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME
COMMAND
root         9  0.0  0.0  18248  3308 ?        Ss   01:14   0:00
/bin/bash
root        27  0.0  0.0  34424  2908 ?        R+   01:14   0:00  \_ ps
auxf
root         1  0.1  0.0  40356  8196 ?        Ssl+ 01:14   0:00
/usr/bin/ruby -- /init.rb
root         8  0.0  0.0  26468  3772 ?        S+   01:14   0:00
/usr/sbin/sshd -D -r
root        19  0.0  0.0  29028  4084 ?        Ss   01:14   0:00  \_
sshd: nsadmin [priv]
nsadmin     21  0.0  0.0  29028  2668 ?        S    01:14   0:00     
\_ sshd: nsadmin at pts/0
nsadmin     22  0.0  0.0  18252  3204 pts/0    Ss+  01:14   0:00       
  \_ -bash

Later, (after login then logout)...

root at 4871a0e3589e:/# ps auxf
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME

auxf
root         1  0.1  0.0  40356  8196 ?        Ssl+ 01:14   0:00
/usr/bin/ruby -- /init.rb
root         8  0.0  0.0  26468  3772 ?        S+   01:14   0:00
/usr/sbin/sshd -D -r
nsadmin     21  0.0  0.0      0     0 ?        Z    01:14   0:00 [sshd]
