X crash and xfce4

[edscott wilson garcia]

It's been several times now that my X session crashes (inevitable when
I'm in the shower or sleeping), and what it strange is that the xfce4
panel is still running (even with no X) hogging up the CPU. After
restarting X it still runs and hogs the CPU until I give it a kill -9.
This is on FreeBSD-4.7, it is not reproduceable on demand, and I have no
idea why it happens and if xfce4 is a victim or culprit. Just FYI.
