Don't know if this is what you're after, but if you're filling in a tile from a single-threaded call (or within a locked thread in engine), there's a "multi threaded" argument in the tile constructor that should make it spawn threads to fill the tile.
But as Colin said, you may want to avoid doing that within an already threaded block in engine.
