Rather than (or at the very least, in addition to) adding a new UUID
generator, let's fix the one(s) we have.
I presume you mean "significantly higher."
Realistically speaking, a random UUID is probably the best you're going
to ever get. I highly suspect that any time- and MAC-address-based
solution is going to suffer from mis-set clocks and misprogrammed MAC
addresses more often than you will have collisions in a 122-bit random
number.
