In Figure 7.1 Three threads call pop() concurrently, showing why you must check threads_in_pop after claiming the nodes to be deleted in try_reclaim().

Thread B calls pop() and is preempted after #19
Thread C calls pop() and is preempted after #18


can't find the corresponding tag #18 #19 in the code.

if i misunderstand, please let me know.
