This is mostly doable now with my changes to put most of the global =20
variables into a structure. Some still exist because arrays in a =20
structure have some odd powerpc performance issues, and a few are =20
initialized at load time which isn't allowed. However they just require =20=

a bit of squeaking to ensure initialization is done at startup time, =20
versus an initialization constant. I bit of work could clean up things =20=

quite a lot so that ALL globals go into a allocated runtime structure.
