The only thing I can think of is a select() with timeout, with
some compromise value that will allow most outputs to complete
without stalling longer than is really convenient.

But it might be just as well to watch the process status for
any non-zero value, and then call the graceful exit procedure.

still the most
efficient library of functions for their purpose for use in
supercomputing applications. Apparently hand-optimized assembler
for specific processors.

two similar things
interchangeable. So we're happy to see that tuple does not have the
features it doesn't need, because it helps in a small way to make Python
code better. If only by giving us a chance to have this little chat once
in a while.

with something a lot like StructSequence.
Meanwhile losing a significant overhead.
I wrote a quickie Python API to SequenceStruct and used it to
make an (x, y) coord type, to compare with a Coord.x,y class.
A list of a million coords used 1/5 space, and took 1/10 the
time to create. Hm.

it's more like tuples have a primary intended purpose,
and some support for other applications. Not white,
but not pure black either.

not much of a historical issue, I'd say, without much
going on in the way of a user community.

a #! or not. csh (the shell language that doesn't
look anything like C, Bill Joy's attempt at language design
before he started over with Java) does that only if the first
line is "#"; otherwise it invokes the Bourne shell.

| So you're saying that for should implicitly invoke list (or mayb
part of the
published API for os.py, so it would be unseemly to complain if it
were to change in later versions. So I guess the right thing to do
is write your own spawn function from the ground up. But at least
you have some ideas there about how it might work.

ly where you actually have complete
coverage from unit testing, which not everyone can claim and I'm sure
even fewer really have. And like the man said, you're doing that work
to find a lot of things that the compiler could have found for you.
