Hi Hauke,

Fix is in svn r1932.  It paradoxically may speed up unbound as it needs
to allocate less memory during validation of a chain of trust.  In your
setup, it may be the opposite as it has to generate network queries to
chase after a SOA record to return to the client.

Best regards,
   Wouter
