Temporary fix for Issue 636 by turning off the caching of the page's entities. This also means that pagination is turned back on because querying all 1000 projects every time will take too long.

r"""
Using simplejson from the shell to validate and
pretty-print::
    
    $ echo '{"json":"obj"}' | python -msimplejson
    {
        "json": "obj"
    }
    $ echo '{ 1.2:3.4}' | python -msimplejson
    Expecting property name: line 1 column 2 (char 2)

Note that the JSON produced by this module's default settings
is a subset of YAML, so it may be used as a serializer for that as well.
