I know you think everthing is a nail because you like hammers, but if
Steve's problem doesn't thrash the TLB, your entire email is not
relevant. Few programs thrash the TLB. There are some programs
sensitive to memory latency, but you only consider memory latency with
TLB thrashing, which is much less common.
In short: this probably isn't a nail.
