Well, I've ensured that /var/cache/apache exists; after that it's pretty
much apache's responsibility (and indeed it does create the heirarchy
below, based upon a config directive for the derired depth.)

The problem that it's having, apparently, is that when you have caching
enabled, it creates a temp-file for every request, and then links it to
a path/filename that is meaningful to it if it discovers that it should
cache the response.  And the errors that I"m getting apparently stem
from the fact that such an object already exists during this
rename-phase.  The question is why does it fail for certain, random
requests and not for all of them?
