The PyPy team have started building libpypy-c.so in their official releases. Now using pypy with uWSGI should be way easier:
The fastrouter got post-buffering:
http://uwsgi-docs.readthedocs.org/en/latest/Fastrouter.html#post-buffering-mode-uwsgi-2-0-9
The psgi/perl plugin exposes the uwsgi::opt hash, reporting the whole instance key-value configuration
This is like –collect-header but the collected header is not returned to the client
This is like the ‘workers’ target, but forward the signal only to non-cheaper workers
The http internal router exposes a new mode called ‘httpdumb’ that does not change headers before forwarding the request
