So the speedup will definitely be less than 2, the only question that remains is how much less. If it's 1.5, well, that may be worth it. If it's just 1.0001 or something like that (or even less than one) it would be dubious.
Threads for rendering are a non-starter right now, at minimum unless we can entirely remove the use of SPStyle from NRArenaItem -- the locking issues are just too complex otherwise, and it is likely that we'd simply end up having to serialize the rendering threads, leading to something like that 1.0001 scenario.
(we'd also need to be careful about using the garbage collector in conjunction with multiple threads, but that's not an insurmountable problem in itself)
