That's because TSVN does the lengthy process of updating each
intermediate folder individually.
So it does the:
   $ svn up --depth empty trunk
   $ svn up --depth empty trunk/subversion
   $ svn up --depth empty trunk/subversion/tests
   $ svn up trunk/subversion/tests/cmdline
without asking the user but just does this (if the folders don't exist yet).

But I would be happy if the svn lib would do that automatically with a
new flag.
