Homework: Reading questions

Submit two items to the submission website (see link in the navigation bar at the top of the page):

Submit your own question about the paper (e.g., what you find most confusing about the paper or the paper's general context/problem), before lecture (i.e., 1pm). You cannot use the question below. To the extent possible, during lecture we will try to answer questions submitted beforehand.
Submit your answer for the question below, before the beginning of the lecture.

Answer the following question:

DFSCQ uses two allocators to prevent improper block reuse (as described in section 6.1). What problem would occur if DFSCQ used only one allocator? How would the problem manifest itself at the level of tree sequences, and what would prevent the proofs from going through?
