Looks like ods-signerd ran out of memory after a few days

This is for a 1M test zone, no optout, on a machine with 8GB of RAM.
This is using 1.4.0a1 with the delete rrset/nsec3 patch applied.
It has signed this zone repeatedly before, so my guess is that there is
a leak causing this to happen over the course of a few days. I have
added smoe memory statistics logging to confirm this.
On restarting the signer I got :
ods-signerd: signer/rrset.c:667: rrset_sign: assertion ctx failed
(note that the machine is using ldns 1.6.13rc1)
