Hi everyone, i am pleased to announce a new major release of the uWSGI project.

The 0.9.9 version focuses on optimizations in various area, an improved spooler and native gevent support.

A new python-specific feature is the 'pyshell': adding --pyshell to your options will run a python shell
in the uwsgi environment (useful for testing the uwsgi api).

The rack plugin has been improved and the old-sharedarea has been revamped to support 64bit.

Pump (an alternative to WSGI) support has been added, it is only a bunch of lines, so do not flame about it :)

A new Emperor mode, called Tyrant, is available for highly-untrusted environments.

This is the first release linkable as a shared library (will be the base for pypy support). Look
at skel.c in source distribution for an example.
