Curious -- why do you think it would be that much work?

I admit I haven't looked into gas code, but naively it can't
be all that difficult to e.g. run gas as a thread and 
pass the text input through some shared memory buffer?

That would likely not speed up thinks too much, but
it could be a starting for more short cuts.
