previous zip.* split up into archive, zip and compression. add O(1) lookup via memento. add support for writing Zip archive. simplify IO by having compression module allow queuing input buffers. file: split up into file, file_Io, file_cache. add atom_fn that enables string comparison via pointer compare. (stores all filenames/paths in one place). add statistics gathering. file_cache: landlord algorithm for caching files as well as LRU block cache. file_io: aio code that splits transfers into blocks revamped and made into class. vfs: filelist/trace code moved into new vfs_optimizer. add caching logic to vfs_load. vfs_optimizer: will generate zip archive (to replace current archive builder script). not yet done vfs_tree: major cleanup - now has nice base class rather than union hackery. This was SVN commit r3420.
