OK, so I wonder if some other locale is set, then grep is converting
multi-byte chars to wide chars and then doing comparison. Years ago
I've benchmarked similar conversions with iconv() and it wasn't great.

Or could be something else completely different. Best thing to do is
profile it. Can DTrace be used to profile shared library functions?
