* Special Thanks *

Lukasz Mierzwa for its incredible amount of test reports with complex
configurations

Giacomo Bagnoli for the KSM idea

Graham Dumpleton (mod_wsgi/newrelic) for help in addressing various
threading issues in the python plugin

* Issues *

A bunch of patches are left out from 1.0, they will be committed in the
future

- you cannot compile the rack plugin with the spooler disabled

- the httprouter subscription system is not solid as the fastrouter one -
support for multiple perl interpreters is post-poned to 1.1

- the graphite/carbon plugin should export more metrics

* Notes *

uWSGI 1.0 is the new LTS release

KSM does not grant you memory gain, it is completely app-dependent

The ruby/rack plugin has an extremely aggressive GC policy, do not expect
extreme performance without tuning it

If you run uWSGI on some hosting provider/PaaS supporting only HTTP, be
sure to use --http-socket instead of --http (extreme performance gain)
