It seems that dbus-launch doesn't exit when the child dbus-daemon is killed. In GDM we use a single X server to run the GDM greeter session and the new user's session. We close down the greeter session by, among other things, killing the pid returned by dbus-launch. However, after a user login dbus-launch is still running. #0 0x008de416 in __kernel_vsyscall () #1 0x001e619d in ___newselect_nocancel () from /lib/libc.so.6 #2 0x08049776 in kill_bus_when_session_ends () at dbus-launch.c:491 #3 0x0804ab68 in babysit (argc=2, argv=0xbfadd524) at dbus-launch.c:651 #4 main (argc=2, argv=0xbfadd524) at dbus-launch.c:1015 dbus-1.2.24-1.fc13.i686
