No, and as Ben mentions, it gets better gradually. But it is a huge
mountain to move, and it moves slowly, as you point out yourself with
the python patches,

While I generally agree with the point you make -- that we have
appropriate kernel interfaces that allow the kernel to decide wisely
when to sleep -- I have to say that making apps suspend-aware and
keeping our dcon tricks is still important for some use cases. e-books
and slide-ware (powerpoint) make the (ahem) point.
