Shared data cache using memory mapped files

This module implements a shared data cache, using memory mapped files. If routines are provided which interact with the underlying data, access to the cache is completely transparent, and the module handles all the details of refreshing cache contents, and updating underlying data, if necessary.

Cache entries are assigned to "buckets" within the cache file, depending on the key. Within each bucket, entries are stored approximately in order of last access, so that frequently accessed entries will move to the head of the bucket, thus decreasing access time. Concurrent accesses to the same bucket are prevented by file locking of the relevant section of the cache file.
