You mean "doesn't fit my current plan" I think. I see almost no bugzilla APM reports. It's been solid for years. It makes a big difference on older systems as it drops the clock. If we are going to drop this we should probaly also drop APM support entirely and 386/486 support. If not IMHO it should stay. Various embedded platforms are still using ancient hardware setups. This is a small stable piece of code that has required no maintainance in years Furthermore we have a feature removal process. Mark it down to be removed in July 2013 if there are no objections, and then wait as per proper process. NAK Alan
