Fortunately, I was able to open the link to see the issue was with
the bm_app_uri benchmark being slower.

I tried some optimizations, but it's still slower than 2.1.5 on my
Haswell E3-1230 v3 server:

  http://80x24.org/spew/m/ugly-uri-optimizations / r48922.txt

Unfortunately, these make evaluating effects of any future compile.c
optimizations more difficult.

benchmark results:
minimum results in each 10 measurements.
Execution time (sec)
name	2.1.5	trunk	built
app_uri	0.484	0.584	0.500

Speedup ratio: compare with the result of `2.1.5' (greater is better)
name	trunk	built
app_uri	0.829	0.968

naruse: any thoughts?
