All of the data sharing tools take the logistics of multi-process read/write situations into account, although they do it in different ways. Some use file locking, others use semaphores, and still others use tricks like atomic file renames. The ones I mentioned in this thead (MLDBM::Sync and Cache::Cache) are both written to provide safe multi-process access. - Perrin
