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...
