Just to clarify. I didn't mean glib mainloop in particular, just the 
serialization concept.

What happens during coldplug is for each device a hotplug event 
structure is allocated and queued (hotplug_event_enqueue()). Nothing get 
processed for now, no probing, not even TDL. At the end of this process 
there is only one very long queue of synthesized hotplug events.

Then hotplug_event_process_queue() gets called and that's when things 
start happening. An event gets unqueued, a device object is put on TDL, 
it goes through three phases: preprobing, probing (when probe is run), 
post-probing (when callouts are run). All this happens sequentially, 
there is no parallelization here (regretfully, as was discussed some 
time ago). Once a device is fully processed, it is moved to GDL (or 
thrown away), and hotplug_event_process_queue() is called again. Until 
the queue is empty.

So you should be able to do your stuff in post-probing. Here's an 
example from blockdev:

	/* probe the device */
	hald_runner_run(d,
			"hald-probe-storage", NULL,
			HAL_HELPER_TIMEOUT,
			add_blockdev_probing_helper_done,
			(gpointer) end_token, NULL);

Hald will wait until the hald-probe-storage process exits and call 
add_blockdev_probing_helper_done(). That's when it can consume the 
properties collected by the probe and do the right thing.
