This tracks the amount of scan work in terms of scanned pointers during the concurrent mark phase. We'll use this information to estimate scan work for the next cycle. Currently this aggregates the work counter in gcWork and dispose atomically aggregates this into a global work counter. dispose happens relatively infrequently, so the contention on the global counter should be low. If this turns out to be an issue, we can reduce the number of disposes, and if it's still a problem, we can switch to per-P counters.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
