Yes.

I currently block, and haven't spent any effort at doing it properly(and will 
probably continue to post pone it until the push-parser stuff has been 
released). An input buffer is built asyncronously, and once it's complete, I 
let the bison/tokenizer loose. That helps at least a bit; during the time the 
parser executes it doesn't block because of waiting on IO, it is only the 
computation time.

Thanks for the clarifications.
