Hmm, who knows then - maybe the issue is only on certain configurations, 
or maybe it vanished due to other changes over time, who knows.

If we can cook up a clean patch to keep the same basic code structure 
but maintain a cache size of 0, that will let us test the theory that 
it's OK to drop the cache, but still keep the code there if it turns out 
to be needed.
