I guess its taking this long to build up because X needs a great deal of inertia so that it can stay in a highly interactive state right? If so then it seems the interactivity estimator does not have enough information to work properly for X. In which case maybe X needs to be reniced, or backboosted, or have _something_ done to help out. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
