Merge of r3966, r3967, r3968, r3969, r3970, r3971: Cache loader improvements: The cache loader performs two tasks: inserting cache objects in inactivity list and evaluating total cache size. Reading just directory is enough for this purpose. Elimination of reading cache files saves at least one disk I/O operation per file.
