The most common idiom is that you have a server that just creates one arena per request. When the request comes in, it creates an arena and uses that throughout the processing of the request, and then destroys it once it is done with that request. I think re-using a single Arena in multiple long-lived threads is more unusual. In your case, is there any way to structure things so that there is a clearly delineated request lifetime that matches the arena lifetime?
