I thought the temporary addresses were cleared at IPL and the permanent
ones were not.  However, don't forget we're talking about a 64-bit
address space; doesn't that mean there are more addresses available than
the number of atoms in the Universe, or something?

So (if that rate of growth remains constant) it would take 200 months to
go from zero to 100%; that's over sixteen years.  You'll have upgraded
the _hardware_ long before that, never mind the OS.  Though I speak as
one looking at a development partition which is currently showing % perm
addresses 0.018 and % temp addresses 0.042, so it's easy to be
complacent.

Cheers,

Martin.
