	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 ...
