OSH Parser Performance
We time $sh -n $file for various files under various shells, and repeat then
run under cachegrind for stable metrics.

Raw files
Summary
Instructions Per Line (via cachegrind)
Lower numbers are generally better, but each shell recognizes a different
language, and OSH uses a more thorough parsing algorithm. In thousands of
"I refs".

(zsh isn't measured because zsh -n unexpectedly forks.)
Average Parsing Rate, Measured on Two Machines (lines/ms)
Shell startup time is included in the elapsed time measurements, but long files
are chosen to minimize its effect.
