Wow. Presumably lock of entire branch is not the primary use case for
'svn lock'. You can actually do:

        svn cp ^/branches/release ^/branches/1_41_0_final
          svn sw ^/branches/1_41_0_final

as the first step in release preparation. That's likely
to be much faster.

(The ^ syntax works only if you're in a working copy).

Well, given that git does not have locks, it's a trick question. You
can write a hook to disable commits to a specific branch, and install
that hook in no time -- but you can do the same in subversion (or use
path-based authorization). In both cases, you need direct access to server.
