[boost] [1.41.0] Beta planned for next week

Looks like we are on schedule for a 1.41.0 beta next week. Now would be a good time for developers to: * Merge any stable changes from trunk to release. You can tell if there are unmerged trunk changes with the svn diff command, or use trunk/tools/release/unmerged.bat. * Check http://beta.boost.org/development/tests/release/developer/summary.html to make sure your library's tests are clean.
