<snip/> IMO the only way to solve this transparently is to more accressively expire and limit the number of continuations. It would make sense to come up with a LRU list of continuations per session. This list has a maximum size that can defined. So the required maximum can is predictable. Generating more continuations means using free slots or throwing away the oldest ones in that LRU list. The janitor would basically only go through the list and expire to free the slots in that list.
