Afaik it is implemented in the checksynchronize call in a platform dependent
manner. It assumes that you run checksynchronize in the idle event of your
eventloop though. (which should be the case for LCL implementations)

If you mean integrate with your own eventloop, then yes, make sure that your
idle event in your eventloop calls checksyncrhonize.
