• Issue:
  I use the lain.widget.pulse widget to get a volume widget on my panel. I have this code:

local myvol = lain.widget.pulse {
   settings = function()
      vol = "Vol: " .. volume_now.left .. "%"
      if volume_now.muted == "yes" then
	 vol = "Vol: mute"
      end
      widget:set_markup(vol)
   end

and this on my keybindings:

awful.key({}, "XF86AudioLowerVolume",
   function()
      os.execute(string.format("pactl set-sink-volume %s +1%%", volume.device))
      myvol.update()
   end,
   {description="Volume down", group="Apps"}),

• expected behavior: When I press the XF86AudioLowerVolume button the widget should update instantly. I change timeout = 0 but the CPU goes wild to 80% or more.

• Actual behaviour: The widget updates after a few seconds.

• steps to reproduce the problem: Press the XF86AudioLowerVolume button. it happens the same with other buttons.
