You can use just a single repo, and the commands are the same, s/sh common\/bin\/hgforest.sh/hg/. But,

 1) your branch name is not guaranteed to available in other repos if/when you need it,

 2) your branch will not have a consistent view of the forest.

     Other repos, using the default branch, will continue to be updated
     with changes from jdk9/dev, which may cause build failures
     as your branch will have to be manually synced with the
     default branch.

I have not experimented too much with queues on branches, but it appears to push and pop simple patches fine for me. Of course, you need to 'qpop -a' before updating between branches otherwise it gets confused, but then this is no different from a normal 'hg update -r’, without branches.

> Is it easy to push anything to the default branch if I am mostly working on my own branch? Also, is there a server-side hook that rejects such pushes?

There is no hook preventing pushes to the default branch. Please be careful.

If this becomes an issue over time, then we can look at the possibility of adding such a hook. I would like to get some experience with using branches and see how it goes before deciding if this is necessary.
