ProxyCommand commands don't exit

I've noticed that when I use ProxyCommand commands to connect, the
commands do not exit when ssh exits.  This results in a bunch of commands
piling up on the machine over time.

I experimented with four machines:

linux-2.2.19+patches, openssh-3.0.1p1
linux-2.2.14+patches, openssh-3.0.1p1
freebsd-4.5-stable,   openssh-2.9 localisations 20020307
freebsd-4.3-stalbe,   openssh-3.0.2

and in all combinations, the proxy command persisted after the client
exited.

luca/home/jason-1049: ps x
  PID TTY      STAT   TIME COMMAND
15245 pts/64   S      0:00 -zsh
16258 pts/64   R      0:00 ps x

luca/home/jason-1050: ssh -o ProxyCommand="nc hermione 22" hermione true
Enter passphrase for key '/home/jason/.ssh/id_dsa':
otp-md5 495 he4606 ext
S/Key Password: [successful authentication]

luca/home/jason-1051: ps x
  PID TTY      STAT   TIME COMMAND
15245 pts/64   S      0:00 -zsh
16265 pts/64   S      0:00 nc hermione 22
16273 pts/64   R      0:00 ps x


For completeness, I also used all of opie, rsa, passwd and hostbased auth
to test, and nothing changed.


Is this a bug, a feature, or a misunderstanding?
