For this release I refactored the code involved with disk_io, it is more modular now and has fewer inter-dependencies.
I have disabled all of the --xxxxxx-security options in import_file (they controlled how scattered the file was on the disk). I plan to re-introduce them at some point in the future, but for now it stores files as contiguous as possible.
This will be the last version 29 release. I plan to change the chunk_info table in the next release. Also future package releases will be done under the "Objectify" project.
Please note that the CVS for Objectify and release packages are in under the New World OS project: http://sourceforge.net/projects/nwos
