Use a big hammer: Create a new global variable, set it to 1 while
resuming and back to 0 after the tasks have been thawed. While the
variable is nonzero, print in the log the list pointers in
cwq->worklist just before executing the list_del_init(). Maybe also
print some other interesting information about cwq.
