- * Calls to this function are serialized due to a potential deadlock: Say there
- * is a nodemap A and a nodemap B that both need to reclassify their members.
- * If there is a member in nodemap A that should be in nodemap B, reclassify
- * will attempt to add the member to nodemap B. If nodemap B is also
- * reclassifying its members, then its hash is locked and nodemap A's attempt
- * to add will block and wait for nodemap B's reclassify to finish. If
- * nodemap B's reclassify then attempts to reclassify a member that should be
- * in nodemap A, it will also try add the member to nodemap A's locked hash,
- * causing a deadlock.
