Is NearestNeighbourSearch() thread safe?

Hi!

Is the NearestNeighbourSearch method thread safe?

Couldnt find anything explicitly on this in the docs and it was not 100% clear for me after reading the code, so thought Id ask.

Thanks, Rolf

It should be (at least when you're using it in a read-only fashion), but the actual implementation is in KdTree.
