I think we need to remove await here now. Otherwise double CTRL+c doesn't force exit if test threads are stuck/slow.

Lines 78 to 82 in 847d322

	if (ctx.runningPromise) {
	if (cancelKeys.includes(name)) {
	await ctx.cancelCurrentRun('keyboard-input')
	}
	return

E: Tested locally, works fine. The _keypressHandler is not awaited so no need to remove that other await ctx.cancelCurrentRun.
