How can I permamently tenure a datastructure.

Hi,
I have a big big in memory datastructure (~1gb) (and this is just about the limit for most JVMs as well).
I have had some success earlier in LISP on a similar problem, by basically loading the datastructure, and the telling the GC that it is never, ever, supposed to look at it.
I've been looking through the 1.3.1 hotspot JVM hints, and can't find how to get stuff into the "Perm" area. Any other ideas ?
Many thanks,
Winton
