With the new patch I see no benefits on the same micro-benchmarks you posted (it is even slower for the smaller case) on a quad-core 64-bit F15 box:

BEFORE:

$ ./python -mtimeit "def y(n):" "  for x in range(n):" "    yield  x" "sum(y(10))"
1000000 loops, best of 3: 1.33 usec per loop
$ ./python -mtimeit "def y(n):" "  for x in range(n):" "    yield  x" "sum(y(1000000))"
10 loops, best of 3: 66 msec per loop

AFTER:

$ ./python -mtimeit "def y(n):" "  for x in range(n):" "    yield  x" "sum(y(10))"
1000000 loops, best of 3: 1.45 usec per loop
$ ./python -mtimeit "def y(n):" "  for x in range(n):" "    yield  x" "sum(y(1000000))"
10 loops, best of 3: 65.8 msec per loop
