sys.exit("Quit") raised correctly but then caught by event loop

[teh]

To reproduce press CTRL+\ in a fresh ipython console (I'm using 7.1.1).

Expected behaviour: ipython quits
Observed behaviour: The following stack trace (chopped off long paths for readability):

Unhandled exception in event loop:

Meh... thanks for the report. I've the feeling this isgoing to be hackish to fix.
