Handle interrupts better in the notebook

[boothby]

Interrupting the notebook is less robust than it used to be. The attached worksheet is an example where the notebook fails to interrupt. When this happens, the notebook acts as though it's interrupted.

I have verified this. It is a very bad bug, since it means that one thinks the notebook got interrupted, but it didn't. This results in a seemingly totally broken worksheet, which must cause massive confusion to everybody, to say the least.

(Oh, and it is surely my fault since I rewrote the interrupt code in the notebook separation.)

The patch at #5712 should fix the problem.

Hard to say what's going on here. My guess would be a bare except: somewhere catching the KeyboardInterrupt.

I cannot reproduce the problem anymore in recent versions of Sage, so I assume it got fixed by #9678.
