My use case is installing a signal handler to force IPython to exit.\n\nI would like something like this to work:\n\n```\nIn [1]: import sys, signal\n\nIn [2]: def exit_now(*args): sys.exit()\n\nIn [3]: signal.signal(signal.SIGALRM, exit_now)\nOut[3]: 0\n\nIn [4]: signal.alarm(2)\nOut[4]: 0\n\nIn [5]:\n```\n\nIt used to be that forcing an EOF on stdin would work, but `prompt_toolkit` does not handle that correctly anymore.
