+ The default behaviour of storeOpen() (ie, disk object fetches) is to not
+ the object from disk if the load of that store directory is too high.
+ This may not be suitable in all situations. One thing to keep in mind
+ is that the subsequent "MISS" may end up storing a fresh copy of the
+ object in the disk store, possibly in another cache_dir (one which isn't
+ overloaded.)
+ Please note that individual store dir modules will implement their own
+ load checking and may decide to not return the object. This will have
+ the same effect as having storeOpen() itself fail.
+
+ Set this to "off" to always allow storeOpen() to go to the store_dir
+ layer.
