With timeline semaphores we can avoid creating objects. Instead of creating an event, grab the current tick from the scheduler and flush the current command buffer. When the fence has to be queried/waited, we can do so against the master semaphore instead of spinning on an event. If Vulkan supported NVN like events or fences, we could signal from the command buffer and wait for that without splitting things in two separate command buffers.
