There are no benefits in trying to queue up rendering commands to the GPU in parallel. Rendering happens in parallel on the GPU already and sending in the commands in parallel just creates a lot of overhead in the driver which must check for synchronization points in the command stream and may need to reorder things.
Also multithreaded OpenGL operation is tricky to get right.
