Campaign Classic v7 - Multithreading API

We are currently implementing the CRM connector between v7 and MS Dynamics 9 on prem. Microsoft is asking whether or not the API will handle multi-threading. I can't find any documentation around this and none of my contacts at Adobe have been able to answer this question. Any forum Experts or Adobe Staff that can answer this question. This is time sensitive as we are Architecting the solution with them now.
