Xavier de Gaye added the comment:
Hum, I misunderstood the meaning of persistency in this context. It is the
uniqueness that is persistent. Sorry for the noise, closing now.

New submission from Xavier de Gaye :
UUIDs are unique and persistent across time and space.
UUIDs generated using the getnode() function of the uuid module on a plaform
where getnode() cannot use the MAC address are based on a random number created
for that purpose and are therefore transient
