Cache.
Association tables (from any kind of database)
that keep the most recently used values in memory.
It is also possible to set a maximum lifetime for data in the cache.
<p>
It is based on a structure of doubly linked lists with maximum size,
that keeps only the mostly recently used values first, if you call the <code class="code">up</code>
function each time you use a value.
(Insertion, remove and "up" in time 1).
This structure is exported, so that it can be used in other cases.
<p>
Not (preemptive) thread safe.<br>
