Alex, it's disappointing to me too! 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...

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 ...
