I have some code that blows up the heap and I'm not sure why. I've reduced
it down to the following.
I've tried to make sure the atom doesn't have boundless growth and I didn't
think 'while' hangs on to the head of sequences so I'm embarrassed to say
I'm stumped.
(defn leaks-memory
[]
(let [mem (atom [])
chunksize 1000
threshold 2000]
(while true
(swap! mem conj (rand-int 100))
; every 'chunksize' item past 'threshold'
(when (and (= 0 (mod (count @mem) chunksize))
(> (count @mem) threshold))
(swap! mem subvec chunksize)))))
