Kill remote in response to client death?

If execute, say, "ssh blue sleep 600", then a ps on blue shows me something like this:

     UID   PID  PPID  C    STIME TTY      TIME CMD
  jhayes 15608 15606  0 15:25:16 ?        0:00 /usr/local/openssh/sbin/sshd
  jhayes 15609 15608  1 15:25:16 ?        0:00 tcsh -c sleep 600
  jhayes 15621 15609  0 15:25:17 ?        0:00 sleep 600

If I then kill the ssh client, a subsequent ps on blue shows:

     UID   PID  PPID  C    STIME TTY      TIME CMD
  jhayes 15609     1  0 15:25:16 ?        0:00 tcsh -c sleep 600
  jhayes 15621 15609  0 15:25:17 ?        0:00 sleep 600

So the ssh command creates a hierarchy of three processes on blue, and killing it only terminates the topmost of the three. I want to purge all three processes in response to a ^C on the client side. Is there any way to get ssh to behave this way? A process that writes to stdout/err will generate a SIGPIPE, but I'd like to kill it even if it produces no output.

Thanks,
