(04:03:46) powerman-asdf: leetspete: my pidgin runs 24x7 and keep logs, so if I'll know wanted time period I can provide logs (04:42:53) leetspete: raphaelsc: It looks like a reasonable scheduler. :) (04:43:36) raphaelsc: Yeah I only spend few hours working on it (04:43:49) leetspete: powerman-asdf: infernjoe was asking a few days ago about if the logs in here were anywhere on the web. I don't know the period, think he just wanted to browse. (04:43:50) raphaelsc: I would have to implement a more consistent algorithm such as round-robin (04:45:05) leetspete: raphaelsc: Isn't it already round-robin? It looks like it goes through a list, schedules it if it's waiting to run, returns to the beginning if it hits the end. (04:45:45) raphaelsc: Yeah but round-robin also provides a priority scheme (04:46:40) raphaelsc: I'm going to implement a copy-on-write feature soon hehe (04:47:50) raphaelsc: Copy-on-write is also used on page swap (04:48:21) raphaelsc: For forking processes as well (04:48:46) raphaelsc: Many high level programming languages provides such features (04:48:58) raphaelsc: provide* (04:50:04) leetspete: Yeah.
