Yet another possibility would be to pass the interesting attributes
as input to swank:list-threads.  E.g.

(list-threads '(:id :name :status :description :priority :total-runtime))
=>  ((18 "worker" "Active" "" 10 0.2)
     (16 "repl-thread" "Semaphore timed wait" "" 5 0.3))

Perhaps complemented with a function to find out all possible attribute
names.
