I have a question regarding to the index for Xconnect table in Xconnect

In rfc1695 the manager issues a get on atmVpCrossConnectIndexNext to
get the next available index for Xconnect table, upon receiving the
index, the manager issues a set (with RowStatus=CreateAndGo) to create
a Xconnect entry in the table. 

My question is: if there is another request for
atmVpCrossConnectIndexNext comes in from another channel (SVC request or
another manager request) in between the time first get
atmVpCrossConnectIndexNext and set (create) requests, what would happen?

What is the industry practise to solve this racing situation?

Thanks for your help.
