I mostly wanted to stick to the standard library for speed, I assumed 
that calling the BIFs now() and node() would be much more efficient than 
running code to generate a uuid.

Memory-wise, a tuple containing {node(), now()} should use up much less 
space than a 128 bit uuid.

But good to know the code is out there, will come in handy someday I'm sure!
