I think the patch was scrubbed.  Here it is again just in case.

  * instance-table-bootstrapping-bug

  Lazily load the indices-cache to avoid bootstrapping issues: If we do
  not lazy-load the indices cache, it we attempt to initialize it before
  the instance-table is available (thus we cannot map oids to classes --
  deserialize does not really work for complex objects).

that controller-recreate-instance is recursively called in migration

  It results in a recursive call for sb-thread:with-mutex. The
