  * Arranges that Xen library handles (fds etc.) which are currently held
  * by Xen libraries, can no longer be used other than to affect domid.
  *
+ * Does not prevent effects that amount only to
+ *   - denial of service, possibly host-wide, by resource exhaustion etc.
+ *   - leak of not-very-interesting metainformation about other domains
+ *     eg, specifically, event channel signals relating to other domains
+ *
  * If this cannot be achieved, returns -1 and sets errno.
  * If called again with the same domid, it may succeed, or it may
  * fail (even though such a call is potentially meaningful).
