UnixMountMonitor.get
Gets the #GUnixMountMonitor for the current thread-default main context.
The mount monitor can be used to monitor for changes to the list of mounted filesystems as well as the list of mount points (ie: fstab entries).
You must only call [gobject.object.ObjectWrap.unref] on the return value from under the same main context as you called this function.
Returns
the #GUnixMountMonitor.
