I do not necessarily think that it is a good approach to forbid the same
branch to be checked out in two different places, by the way. One reason
people would want to keep multiple workdirs is so that while they are
still working on a branch and are not yet at a good "stop point" to even
make a temporary commit to get interrupted, they find it sometimes
necessary to be able to build the tip of that same branch and even make a
small in-working-tree fixes (which later will be carried back to the
primary branch). The problem arises only when one of the repositories try
to update or delete the branch while it is checked out in another working
tree.

I think of two options:

 - detach from the already locked branch (pretty much like what we do
with tags now)

 - refuse normally but let "checkout -f" do it anyway. However the
checkout lock will remain at the original worktree. If you want to
update branch from the second checkout, do "commit -f" and take
responsibility for your action.
