It seems there are 4 processes running on the remote host when I
started firefox via ssh -X :

han 1939 1895 0 20:28 ? 00:00:00 sshd: han@notty
han 1940 1939 0 20:28 ? 00:00:00 /bin/sh
/usr/lib/firefox-3.6.9/firefox
han 1947 1940 0 20:28 ? 00:00:00 /bin/sh
/usr/lib/firefox-3.6.9/run-mozilla.sh
/usr/lib/firefox-3.6.9/firefox-bin
han 1951 1947 6 20:28 ? 00:00:09
/usr/lib/firefox-3.6.9/firefox-bin

after I closed the firefox window, there is only one process left on
the remote host:

han 1939 1895 0 20:28 ? 00:00:00 sshd: han@notty

I am wondering why this one did not exit.
