Yes, for SN2 this works and is what I presently use here. Somewhere I have/had an instrumented version of the ivt code which allows to to profile fault patterns across regions and such-like, by sucking data our of /proc and making pretty graphs --- I wrote this mostly to ensure what I thought was going on really was and also to get some idea of the distribution of things. Since it doesn't affect non-SN2 users I'm hoping to get something like this merged if nobody objects... --cw
