You can bound the worst case on this and I think stay within the specs (as the specs don't say a lot about it). One way would be to make unix_gc() kick off a thread/tasklet and if the last unix_gc was within 5 seconds then use a timer to defer it - that prevents any user driven "lets cause a ton of gc" cases. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
