Patches requiring adjustment

These are pending patches whose concepts are good, but which are imperfect in implementation or design and need further work, or are simply outdated and need a bit of updating to apply to the current CVS version. This work can be done by anyone; feel free to make improvements even if you're not the original author. If you do think you've fixed whatever issues are raised, reclassify the topic as a PatchProposal to schedule it for another round of CoreTeam evaluation.
