There just isn't anything currently in the library to do this, and I haven't written apps that needs this often enough to have a good feel for what kind of abstraction is needed. However perhaps we can come up with a design for something better? Do you have a suggestion here? I agree with your comment that higher-level abstractions around OS stuff are needed -- I learned system programming long ago, in C, and I'm "happy enough" with the current state of affairs, but I agree that for many people this is a problem, and there's no reason why Python couldn't do better... --Guido van Rossum (home page: http://www.python.org/~guido/) Great questions! Alex and I are both working on answers, I think; we're definitely not ig- noring this. More, in time. One thing of which I'm certain: I do NOT like documentation entries that say things like "select() doesn't really work except under Unix" (still true? Maybe that's been fixed?). As a user, I just find that intolerable. Sufficiently intolerable that I'll help change the situation? Well, I'm working on that part now ...
