kind of. the problem is that all bodies in an island have to be at
the same world time - so what happens when two islands with slightly
different times collide? (i.e. their step sizes are not simple
multiples of each other). is there some kind of time-resynchronization?
what happens? also, if the "safe" step size is set per body, how does
the island step size get set. minimum? some kind of voting?
some experimentation would be required.

of course you can simulate different worlds at different rates, but
the different worlds can not interact.
