L{CGIScript} is a resource which runs child processes according to the CGI
specification.
The implementation is complex due to the fact that it requires asynchronous
IPC with an external process with an unpleasant protocol.

Do various things to conform to the CGI specification.
I will set up the usual slew of environment variables, then spin off a
process.

I am a special version of a CGI script, that uses a specific executable.
This is useful for interfacing with other scripting languages that adhere
to the CGI standard. My C{filter} attribute specifies what executable to
run, and my C{filename} init parameter describes which script to pass to
the first argument of that script.
To customize me for a particular location of a CGI interpreter, override
C{filter}.
@type filter: L{str}
@ivar filter: The absolute path to the executable.
