Ok.  I was trying to stick with the available packages on the target
OS, but might be worth upgrading.

With loglevel debug I have not been able to reproduce the problem.
Although I do notice that mod_cache doesn't seem to do an
If-Modified-Since request when the cache copy expires, which I
expected.  Maybe it does that in 2.2 (or maybe I just don't
understand caching enough to see why that's not done. ;)
