Since the initial release, recorded on-disk cache size was decreased twice for purged content (once during cache purge and once during subsequent cache update). This resulted in recorded on-disk cache size being much smaller than in reality, which could lead to on-disk cache outgrowing defined "max_size" parameter. Patch from Pyry Hakulinen. END
