long chains of Deferred values hang #48
Description
i came across this while debugging another problem
(defn chain-delay-deferred
[n t]
(let [f (manifold.deferred/deferred)]
(future (Thread/sleep t) (manifold.deferred/success! f 100))
(reduce (fn [d i] (manifold.deferred/chain d (fn [v] (+ v i))))
f
(range 0 n))))
@(chain-delay-deferred 100 1000) ;; 5050
@(chain-delay-deferred 100000 1000) ;; hangs
there are some values of n where it hangs on some runs and returns on other runs. on my machine
@(chain-delay-deferred 4567 1000)
seems to hang about half the time
i ran this against the current tip of master 4e1fff70c5380b33e9cc2f50f03ce16af6d393b4, but i was observing the same problem against 0.1.1-alpha3
