Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case there are 18 comparisons, you can thus
expect the following amount of false-positive results:
0.90 false positives, when considering a 5% risk acceptance (*, **, ***),
0.18 false positives, when considering a 1% risk acceptance (**, ***),
0.02 false positives, when considering a 0.1% risk acceptance (***)
I'll see if there's anything else we can optimize to compensate for these regressions. Also, I'm not sure if we can break the HTTPParser API. It's not documented, and this PR removes the .reinitialize() method.
@mcollina @Flarna @AndreasMadsen PTAL a let me know what you think.

Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case there are 217 comparisons, you can thus
expect the following amount of false-positive results:
10.85 false positives, when considering a 5% risk acceptance (*, **, ***),
2.17 false positives, when considering a 1% risk acceptance (**, ***),
0.22 false positives, when considering a 0.1% risk acceptance (***)
