XFrom README:
X This module implements a least recently used (LRU) cache in memory
X through a tie interface. Any time data is stored in the tied hash, that
X key/value pair has an entry time associated with it, and as the cache
X fills up, those members of the cache that are the oldest are removed to
X make room for new entries.
X
X So, the cache only "remembers" the last written entries, up to the size
X of the cache. This can be especially useful if you access great amounts
X of data, but only access a minority of the data a majority of the time.
X
X The implementation is a hash, for quick lookups, overlaying a doubly
X linked list for quick insertion and deletion. On a WinNT PII 300, writes
X to the hash were done at a rate 3100 per second, and reads from the hash
X at 6300 per second. Work has been done to optimize refreshing cache
X entries that are frequently read from, code like $cache{entry}, which
X moves the entry to the end of the linked list internally.
