[sldev] High-prim vehicles using phantom (Re: Havok4...)

[Andre Roche]

Unfortunately, according to Andrew and Sidewinder, the real issue with
vehicles above the 31 prim limit isn't physics interactions.  It's
region hand-off.  I'm not really sure exactly -what- the problem is,
but the claim is that it's not physics interactions themselves that
limit the prim count.
