record:host with exclude and multi-threaded environment

[#1]

Hi guys - 

We are running into an issue where 2+ different hosts are being created using same IP address in a multi-threaded environment and we were wondering if a similar issue has been addressed in this forum already. I did some digging and searching and did not find any solution. The closet to what we are experiencing can be found at https://community.infoblox.com/forum/ddi/recordhost-and-multi-threaded-environment. 

Ideally what we want is the ability to use host objects(record:host or record:a) to reserve the next available IP while ensuring that the IP reserved is not a member of the IPs specified in the *exclude* list - 

Many thanks in advance for your help and support. We appreciate

Regards
