  So, I think I've found at least one reliable (repeatable) way to crash sway.

  Starting up sway, I pop one floating window (xterm).  Run this little script:

	#!/bin/sh

	for y in 0 1 # 2 3 4 5 6 7 8 9
	    do
	    for x in 0 1 2 3 4 5 6 7 8 9
		do
			urxvt &
			echo $y $x
			sleep 1
		done
	    done

  It makes it to ~17 or (tiled) urxvt windows so before sway "crashes".  IE,
bails out to virtual terminal (where I can log in remotely and run vidcontrol
to get my original console).  I've done that about 8 times in a row.

  It died about 17 debugging lines into a ~226-line series for opening a urxvt window.

  If you run it without the sleep, it'll complain that the X display isn't available but
not crash, at least in my simple test of ~20 runs.
