Details:

velocities <v_max>

should set random velocities < v_max to all particles. As soon as I set the
time_step, the resultant velocities are garbage. Despite some effort, I was
unable to figure out where it goes wrong.

script:
part 0 pos 1.0 1.0 1.0;
puts [velocities 10.0]
puts [part]
setmd time_step 0.0125
puts [velocities 10.0]
puts [part]

output:
4.512527
{0 pos 1.0 1.0 1.0 type 0 mass 1.0 q 0.0 v -0.09661151566384918
