I'm working on a patch to disable wildcard calculation when we're doing things like pushing stats and don't actually need to know what the mask should be. I had a question for you about your staged match patch on this. I notice that you disable the staged matching when wildcards aren't passed in. My guess would be, that even if we don't need the wildcards the staged matching would be slightly faster than the old algorithm because on average we have to compute less hash. If this is true (again not sure either way), should we change the code to *always* do the staged lookup?
