I really wouldn't worry about time-based uuid if you're grabbing them
from uuidgen. Yes, if you're generating thousands of uuid's in
parallel via the C interface, it's possible that you potentially force
a collision. But via the command-line interface of uuidgen?
There are plenty of other things to worry about.
