The continuations are reclaimed independently from the GC. They are
always reachable, because I never know when a new request will come in
for them. (For example, someone could go to a site, write down the
URL, store it in a safety deposit box with instructions for their
grand-child to go to the site on their 50th birthday, etc.)

It would be cool to do something GC-like by inspecting all current
requests during a reclamation phase, but it's not on my radar. (And
actually wouldn't fix this problem, because until the upload is
complete there is no request to observe.)
