<p>Contains a cache of read-only blocks of data, allowing references to

them to be returned. Entries in the cache are never removed.
|

Entries are keyed on the offset and size of the read.

Currently overlapping reads are considered separate reads.</p>

<p>This is primarily intended for environments where memory mapped files

the file size.</p>
