Thanks for the detailed explanation.

After w1 and o2 have been set to #f, is there anything preventing the space
for either of them to be reclaimed anytime? In particular,
- is the fact that o1 hasn't been reclaimed yet keeping w1 alive?
- will the reference to o2 in w1's action closure prevent it from being
reclaimed before that closure is reclaimed?
A corollary to the latter: if I delay the execution of w1's action closure
for long enough (e.g. by holding onto o1) could I ever get it to execute
with o2_ pointing to freed/invalid memory?
