I object unless you outlaw JNI calls within any Isolate-containing JVM.  Or
you use something like software fault isolation
(http://portal.acm.org/citation.cfm?doid=168619.168635) for all of the
native code -- which will be hard if you are running subsystems like
database managers.

I differ on how long this will take :-)
