Moving back in time ... [GordonM]
Perhaps Christian's stackless Python would enable green threads...
[Guido]
This has been suggested before... While this seems possible at first, all blocking I/O calls would have to be redone to pass control to the thread scheduler, before this would be useful -- a huge task!
I didn't understand this. If I/O calls are left alone, and a green thread hit one, the whole program just sits there waiting for the call to complete, right? But if the same thing happens using "real threads" today, the same thing happens today anyway <wink>. That is, if a thread doesn't release the global lock before a blocking call today, the whole program just sits there etc. Or do you have some other kind of problem in mind here? unconvincedly y'rs - tim
