Update: logs with debug level 3 show this:

2002/01/02 16:45:19| refreshCheck: 'http://www.xfree86.org/isc.gif'
2002/01/02 16:45:19| STALE: age 106 > min 0

2002/01/02 16:45:49| refreshCheck: 'http://www.xfree86.org/xfree86.logo.gif'
2002/01/02 16:45:49| FRESH: age 8540 <= stale_age 9019410

Will look into src/refresh.c:refreshStaleness() for clues tomorrow
