Auto disabling / enabling works.

See ode/test/test_crash.cpp example. After looking this file, you will 
see how to use this feature.

In short, ODE automatically enables all disabled bodies that come in 
contact with enabled bodies. But you have to take care of when to 
disable bodies (programmatically).

You can disable bodies e.g. on cases when they move very little, disable 
every body that has angular velocity < X and linear velocity < Y for N 
steps. Tweak X,Y and N values yourself. Actually test_crash.cpp on CVS 
head implements this in a single C function, see it yourself.
