This is also how the Apache httpd server works, last I checked. Not the entire server, of course - it's a long-lived program with lots of memory to manage, however when servicing a request, it uses the arena pattern to allocate memory and the entire arena is freed at the end of the request. In fact, its entire memory management model is based on a hierarchy of memory arenas that can only grow and get freed once whatever it was that required their liveness ends. I've had the pleasure to write a plugin for it to handle a certain custom upload protocol.
