I looked at the unbound source code.  It prefetches when it's responding 
to a query, code in daemon/worker.c.  The code is considerably complicated 
by defensive code to deal with the situation where the parent of the 
record to be prefetched has changed since the record was originally 
fetched.  (Feel free to check my work.)  That's probably worth mentioning 
in the I-D.

There is a separate option to prefetch DNSSEC key records.
