This is the sole purpose of the replacement policy: to determine which
old objects to automatically delete to make room for more interesting
new objects when you cache is full.

See the research paper mentioned for a detailed description of the
purpose and effect of the "heap LRU" algorithm. Summary: The "heap
LRU" algorithm exists as a reference to compare the heap
implementation with the implementation of the standard squid lru
algorithm. It provides no benefits (only drawbacks) compared to the
standard Squid lru algorithm.
