I would like to start bringing parts of the executioncontext20091231 branch into the trunk before we create the next release branch. The implementation of the new security design is not finished, but it will be disabled - so everything will still work the same.
My goal is to allow users of the 10.x release to plan for the forthcoming changes, and maybe have the conversion to the new design completed by the release that follows 10.x. I will wait a few days, and if there are no objections I will begin merging the design into the trunk. -Adrian
