[Libvirt-cim] Is virStoragePoolRefresh() synchronous or asynchronous?

Basically, when you call virStoragePoolRefresh(), eg to pickup any new disks that may have just been created under the pool path, when the API returns are you guaranteed that the refresh operation is completed, or might the pool still be refreshing itself? I ask because I understand this refresh operation can be 'expensive', so I'm wondering if in fact things may still be going on in the background after the API returns... - Gareth Dr. Gareth S.
