Well, what's curious is that I thought I was running under X11, but now I
see that I'm not running the server.
What's even stranger is that this isn't happening anymore, or at least it's
not happening today. I guess that means there's some sort of race
condition in play here, which is really annoying.
I'm even running the exact same command line that I was running before
(that is, passing the same parameters to the script that calls the process
that had this problem).
