gnome-vfs sources, file gnome-vfs-job.c, function job_notify. It adds 
idle handler, that calls the callback, to the main loop. It doesn't call 
the callback function by itself in its own thread.

You can use gdb to set up a break point in your function and see how 
execution flow gets to your function and in which thread's context.
