"Reasonably considered"?
In other words, this is a 64-bit random number generator. Sorry, I
think the odds of collision would be uncomfortably high if we were to
use such a thing for OIDs ... certainly so on installations that are
worried about running out of 32-bit OIDs. It sounds to me like uuidgen
is built on the assumption that only relatively small numbers of IDs
will be demanded from it.
