//
// Submit command buffer
//
// Post-submission work Begin execution

// ???? Write timestamp Tgpu
//
// ???? End execution

// The areas of unknown work (????) on the CPU indicate that the CPU may or may not have

// work, querying CPU timestamps before submission and after getting query results give the
// bounds to Tgpu, which could be quite large.
//
// Using VkEvents, the GPU can be made to wait for the CPU and vice versa, in an effort to
// reduce this range. This function implements the following procedure:
//
// CPU GPU
//
// Record command buffer
// with timestamp query
//
// Submit command buffer
//
// Post-submission work Begin execution
//
// ???? Set Event GPUReady
//
// Wait on Event GPUReady Wait on Event CPUReady
//
// Get CPU Time Ts Wait on Event CPUReady
//
// Set Event CPUReady Wait on Event CPUReady
//
// Get CPU Time Tcpu Get GPU Time Tgpu
//
// Wait on Event GPUDone Set Event GPUDone
//
// Get CPU Time Te End Execution
//
// Idle Return query results
//
// Get query results
//
// If Te-Ts > epsilon, a GPU or CPU interruption can be assumed and the operation can be
// retried. Once Te-Ts < epsilon, Tcpu can be taken to presumably match Tgpu. Finding an
// epsilon that's valid for all devices may be difficult, so the loop can be performed only
