Great! That's pretty much the intended use-case of common timeouts: taking advantage of the fact that if you know that a large number of timeouts are all the same value, you can have a priority queue run in O(n) time rather than O(n lg n). I'm glad they turned out to be useful for somebody. (Besides the initial guy who reported the issue, who just wanted us to switch from a heap to a queue because it was faster for _his_ load. Yeah, not gonna do that one. ;) ) yrs, -- Nick *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
