I think you missed the point. It *does* cause everything to be checked
out, but because its in a directory named "everything" you only get that
if you specifically asked for it. This is true of all the other
approaches as well, including putting the t/t/b at the top level. Its
just a matter of what URL you use to check out. For example:

1. Checkout just llvm: svn co
http://llvm.org/svn/llvm-project/llvm/trunk llvm
2. Checkout everything: svn co
http://llvm.org/svn/llvm-project/everything

The summary of this thread is that:

a) doing /trunk/{module}/... is not advised
b) we can use externals to simulate an "everything" dir. That is, we
create
  /everything which has subdirs like llvm, hlvm, test-suite, java,
stacker, etc. which 
  have external links to all the /{module}/trunk dirs but named
{module}.

This gives us the best of both worlds.
