BTW Both Ganesha and kpnfsd behave the same. A recall issued while in layout_get
the layout-get reply will be sent first and then the recall will be sent on the wire.
If the recall was sent before the receive of the layout_get then an error/success is
returned imitatively without ever waiting for recall_reply to return.
