I think that I have seen the custom to use an underscore as first letter of 
private functions (somewhere else but also in the Core). What do you think 
of that?

But more important, there is a locking mechanism missing. New pages could 
be cached while you're busy deleting the cache directory. Will this be a 
problem or is this handled gracefully as a "cache miss"?

page?
