Whenever possible, prefer the safe wrappers withWindowAttributes or safeGetWindowAttributes to getWindowAttributes. Places where these are not applicable are limited to layouts, where there is not good "default value" to give back in case these calls fail. In these cases, we let the exception handling of the layout mechanism handle it and fall back to the Full layout. Fixes: https://github.com/xmonad/xmonad-contrib/issues/146
