[openbox] openbox connected to remote display doesn't know X server gone

[Xavier Toth]

I'm running an X server for remote display purposes (some might call
it an X terminal). The X client starts an openbox session when a user
logs in. If I power off the X server box (something that shouldn't
happen but can) when a user is logged in and then do a ps on the X
client I see that openbox and a number of other processes started by
the openbox session continue to run indefinitely. It appears that
openbox doesn't know that it's X connection has been lost. Is there
anything that can be done to cleanup these dead sessions?
