* - The pruning interval limits the frequency at which the garbage collector
* will try to scan the cache directory to prune expired entries.
* Setting to a negative number disables the pruning.
* - The pruning expiration time indicates to the garbage collector how old an
* entry needs to be to be removed.
* - Finally, the garbage collector can be instructed to prune the cache until
* the occupied space goes below a threshold.
