[Python-Dev] [PEP 3148] futures - execute computations asynchronously

[Brian Quinlan]

I've updated the PEP to include:
- completion callbacks (for interoperability with Twisted Deferreds)
- a pointer to the discussion on stdlig-sig

See:
http://svn.python.org/view/peps/trunk/pep-3148.txt?r1=78618&r2=80679

Rejected ideas:
- Having a registration system for executors

Not yet addressed:
- where the package should live (someone in a "concurrent" package  
seems fine)
- having global executors with unbounded worker counts as a  
convenience [1]

[1] There are a few issues with global executors that need to be  
thought thought through i.e. when should workers be created and when  
should they be terminated. I'd be happy to defer this idea unless  
someone is passionate about it (in which case it would be great if  
they'd step in with concrete ideas).

Cheers,
Brian
