Aha, that sounds reasonable. However, this solution also introduces
the concept of "forbidden" global object, which previously sounded
strange to me. Now this makes a lot more sense. On the other hand, one
cannot effectively load any JS "libraries" which introduce new classes
(say MySQL, HTTP, ...), because these are created as properties of
global object, ok? So any javascript code needs to be run inside an
anonymous function:
(function() {
[code]
})();
because a simple statement "var a = 3;" would pollute the context...

IMHO some form of "save/restore" support would be ideal for this case:
one would be able to generate a snapshot of created context ready for
usage...

Okay. However, note that I do not seek a final and polished solution -
just some ideas and working concepts (with FCGI included, as I was not
brave enought to dive into it!) :)
