Currently, the initial heap size reported in the gctrace line is the heap_live right before sweep termination. However, we triggered GC when heap_live reached next_gc, and there may have been significant allocation between that point and the beginning of sweep termination. Ideally these would be essentially the same, but currently there's scheduler delay when readying the GC goroutine as well as delay from background sweep finalization. We should fix this delay, but in the mean time, to give the user a better idea of how much the heap grew during the whole of garbage collection, report the trigger rather than what the heap size happened to be after the garbage collector finished rolling out of bed. This will also be more useful for heap growth plots.

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.
