18 1. Where are you getting 5% from?
19 2. What context is this "Performance" hit in? gcc would take a
20 "performance" hit because it eats 100% CPU; most nothing else would take
21 a "performance" hit unless the *overhead* pulled CPU usage up to 100%
22 for a time.

24 I guess this is the point where I have to ebuild unpack nbyte and
25 generate SSP benchmarks. Why oh why didn't I bench ssp when I was doing
26 PIC?
