 I don't know yet size of when this is triggered.

 I have a zone.sqlite3 with 100 million entries. If I query for something
 that does not exist, b10-auth hangs. If I kill b10-auth, bind10 will
 restart it and I can do some queries (of labels in the zone).

 If I query for something not in the zone, I get REFUSED (correctly).

 This problem happens with or without caching (-n).

 I straced the hung process for about 10 seconds and got 4951 read and
 lseek lines:
