[ODE] weird plane behavior

[Martijn Faassen]

Hey Daniel,

Thank you very much, that's useful to know. I solved my problems using 
an immovable geoms, and since I want *some* things to actually pass 
through it from the other side, it appears even a flipped half-space 
wouldn't have helped me.

I will update the wiki page, though I'll get around to it only after 
easter, I expect. I'm in the middle of pyweek currently:

And the game we're working on:
