* hf_device_add()
* hf_device_preprobe_and_add()
* hf_device_remove()
* hf_device_remove_children()
* hf_device_remove_tree()
* hf_runner_run_sync()
*
* Since these functions wait by recursing into the GLib main loop,
* main loop callbacks can be executed during the wait and cause
* undesirable side effects. For instance, an USB attach event for a
* child device could be received while the parent device is still
* being processed in hf_usb_probe_device().
*
* Main loop callbacks must therefore do nothing and return if
* hf_is_waiting is true.
