Yep, i can see how it's useful in this context. But i still think the
documented behavior would be useful in other contexts (and it provides a
standard, cross-platform way to actually be sure that the subprocess
actually dies).
It seems like one of three things should happen:
0) the documentation should be changed to describe the actual behavior
1) the behavior should change to match the documentation
2) both behaviors should be available (since there seem to be
reasonable arguments for either use) -- i'm not sure how the user would
choose between them, though.
