Same here: Swen, have you been able to measure a performance
difference? And if so, what was your benchmark? I would be HIGHLY
interested in seeing you how were able to actually measure this.

In talloc, this *is* measurable, at least Tridge did some good
micro-benchmarks showing some real improvement. Can you please
document what you did to get real improvement in this piece of code to
justify cluttering the code?

Before that: NACK.

Thanks, Volker
