   <div class="markdown level0 summary"><p>LurchTable stands for &quot;Least Used Recently Concurrent Hash Table&quot; and has definate
 similarities to both the .NET 4 ConcurrentDictionary as well as Java&apos;s LinkedHashMap.
 This gives you a thread-safe dictionary/hashtable that stores element ordering by
 insertion, updates, or access.  In addition it can be configured to use a &apos;hard-limit&apos;
 count of items that will automatically &apos;pop&apos; the oldest item in the collection.</p>
