In my experience this comes from your finger "bouncing", i.e. you put your
finger on the touch screen and tslib registers a press but right after that your
pressure releases and tslib thinks that you in fact have just clicked on the
touch screen.
With a stylus it would be less likely to happen since the pressure there is larger.
Using double clicks on a touch screen is quite cumbersome and in our GUI style
guidelines the double click is "strongly discouraged" (see
http://wiki.openmoko.org/wiki/GUI_Style_Guidelines#Touch_Screen).
We would need some kind of pressure detection/hysteresis for the touch screen,
but I'm not quite sure if/how we can do this.
