[go-nuts] runtime swiss maps

Hi, The code in the map_swiss.go and map_noswiss.go is virtually the same. Have the swiss tables been implemented yet? https://github.com/golang/go/blob/master/src/runtime/map_swiss.go https://github.com/golang/go/blob/master/src/runtime/map_noswiss.go There is nothing in the map_swiss.go fil

[go-nuts] question about HACKING.md

In the document HACKING.md (https://github.com/golang/go/blob/master/src/runtime/HACKING.md), it states that we can determine if we're running on the user or system stack by running `getg() == getg().m.curg`. However if the output of that equality check is true, does that mean we're on user o
