[This is a consolidated response to this entire thread.]

I choose the GPL3 license because it is the one I prefer.  As with all
such decisions, it was a reasoned one and not taken lightly. There is no
real point in further discussion of the license or why I choose to use
it.  I am aware of the the consequences of my choice and the advantages
and disadvantages of other licenses.  

If the license is not compatible with your requirements, then that is
regrettable.   If this small snippet of code is so useful in concept
then I'm sure a version which you will be able to use will soon become
available.

This code is a gift.  If you cannot use it, then please pass it by and
hopefully something else which suits your needs will arise.  If you can
use it, then that is good.
