when "normal" parallel computations in CPython will be implemented at last?

hi all, are there any information about upcoming availability of parallel computations in CPython without modules like multiprocessing? I mean something like parallel "for" loops, or, at least, something without forking with copying huge amounts of RAM each time and possibility to involve unpiclab

Re: when "normal" parallel computations in CPython will be implemented at last?
