```go
// Delete the initial process and container
func (s *Service) Delete(ctx context.Context, r *ptypes.Empty) (*shimapi.DeleteResponse, error) {
        p, err := s.getInitProcess()
        if err != nil {
                return nil, err
        }
        if err := p.Delete(ctx); err != nil {
                return nil, errdefs.ToGRPC(err)
        }

	// The client might canceled the request but the shim service still
	// moved on. The `delete(s.processes, s.id)` was executed
	// successfully. So the next Delete call will return `container
	// must be created` error. The client side should ignore this
	// issue.

        s.mu.Lock()
        delete(s.processes, s.id)
        s.mu.Unlock()
        s.platform.Close()
        return &shimapi.DeleteResponse{
                ExitStatus: uint32(p.ExitStatus()),
                ExitedAt:   protobuf.ToTimestamp(p.ExitedAt()),
                Pid:        uint32(p.Pid()),
        }, nil
