It was discussed a bit in p5p, I do not know deep details, but do remember that it is not possible to do a task absolutely correctly, at least because you'll never manage XS modules to unload correctly: they may load any DLLs or depend on outside libraries and outside temperature conditions.

However doing some kind of cleaning for any particular case is of course doable: once you understand behaviour of module, you'll manage right unloading at correct time and stopping all required thermometers.

Courage, the Cowardly Dog
