Caching

• Tie::File does none of these things

• Data is read only as necessary

• Read data is cached for efficiency, but only up to the limit you specify:

        tie @FILE, 'Tie::File', $myfile, memory => 20000000;

• (Default: 2 MiB)

• For convenient concurrent access, disable the cache:

        tie @FILE, 'Tie::File', $myfile, memory => 0;

• The cache is managed using an LRU algorithm
