* GVolumeMonitor:

* `GVolumeMonitor` is for listing the user interesting devices and volumes
* on the computer. In other words, what a file selector or file manager
* would show in a sidebar.
*
* `GVolumeMonitor` is not
* thread-default-context aware (see
* [method@GLib.MainContext.push_thread_default]), and so should not be used
* other than from the main thread, with no thread-default-context active.
*
* In order to receive updates about volumes and mounts monitored through GVFS,
* a main loop must be running.
