@johnaohara FYI this could improve the performance of @Route method invocations a little bit. Although I'm not quite sure it would make any significat difference in your use case.

@mkouba i'll try it out, thanks

@johnaohara Did you get a chance to test this branch?

Anyway, I think that it wouldn't hurt to merge this even though we have no perf numbers yet.

Approx 3.3% improvement in throughput for simple plain text test

@johnaohara thanks!

@gsmet Unfortunately, there is a bug in this PR. Thanks @michalszynkiewicz for spotting the problem. I'm going to send a fix shortly.

[gsmet]

Looks like we need more tests :).

[mkouba]

Well, I don't think that regular tests would cover this. It's a race condition... caused by my inattention.
