The details here are unimportant. Since entry cache items hang off of dncache 
items, the only consequence of a "wrong" configuration here is that the entry 
cache could only ever grow to the size of the dncache.

At any rate, the code has been patched to set dncachesize >= cachesize, and 
the manpage updated correspondingly, but there's no critical problem without 
this patch.
