I found a performance optimization in the new pushlog extension. Patch forthcoming.

And deployed to production. Brief log inspection reveals that pushlog wireproto commands are now using only milliseconds of wall/CPU time, as expected. Thanks for the quick review!
How does pushlog perf now compare to before we switched to the extension? Just wondering if we've helped bug 1079788 at all? Though I guess the next big win will be completing bug 1076826.
I don't expect perf via hgweb (json-pushes) to have changed as a result of this rewrite. However, switching consumers to version=2 and polling via startID and limiting the number of pushes returned should make a significant difference. Also, I wrote https://mozilla-version-control-tools.readthedocs.org/en/latest/hgmo/pushlog.html#writing-agents-that-consume-pushlog-data
