That was an estimate. But I do have a cron job that cleans files in
/tmp that are older than about 10 days. That's probably pretty close to
what I'm seeing. Thanks!

Nope, I checked the source. Fvwm does set the DISPLAY variable
explicitly. And if you set it to hostname:0.0 and hostname is the local
host, it forces it to :0.0. I think this is actually a function of the
Xlib function that opens the display.
