How are the existing frontends doing it then? Do they just wait after
a sent command until they receive a reply and take it as the one they're
looking for?

That's why I asked. There are Eclipse, KDevelop and I don't know how
many other frontends it's hard to believe they always wrote a new parser.
And even if they did was it handwritten or generated... I guess then I'm
looking forward to your results :)
