> In HostDBContinuation::lookup_done() if we can't allocate memory in the cache we will free some space (delete_block())
> and then return a NULL.  Also, the error message "out of room in hostdb for reverse DNS data" gets printed
> out.
> This NULL pointer will be dereferenced later when we call reply_to_cont().
