Currently markroot fetches the wbuf to fill from the per-M wbuf cache. The wbuf cache is primarily meant for the write barrier because it produces very little work on each call. There's little point to using the cache in mark root, since each call to markroot is likely to produce a large amount of work (so the slight win on getting it from the cache instead of from the central wbuf lists doesn't matter), and markroot does not dispose the wbuf back to the cache (so most markroot calls won't get anything from the wbuf cache anyway). Instead, just get the wbuf from the central wbuf lists like other work producers. This will simplify later changes.

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.
