Profiling FOTN, during the GC pauses, we spend a lot of time in finalization of Float32Array on the main thread. These should be on the background thread instead.

With this patch my GC pauses in FOTN are down to 113 ms. Still noticeable (that's a loss of about 7 frames), but that's much better than before. This should help 3D stuff quite a bit.
