I guess Python could do it without storing the session ID in a file or database and instead in process state (i.e. application memory, right?), but the effect seems basically the same. Without being per-connection, what is the value of process state?

Caches and stuff. For example, you might establish a database
connection, and then hang onto it for all queries; or maybe you load
up a bunch of user objects and keep them in memory for when you need
them again. Anything that you store in a global (module-level)
variable will hang around.
