Well.. if it isn't harmful in any way, and if we would do it on x86_64, then we should also do it on i686. Having as consistent a baseline as possible is good. As to actually doing it, are there any ramifications due to the potential for tracking additional cpus (timeslice allocation algorithmic changes?) that would be a noticeable performance inpact for people running 2 or 4 cpus?
