Actually, how expensive is this?

lyta:~/> svn log --quiet svn+ssh://cmdev/repos/branches | head -2

svn: Can't write to stream: Broken pipe

It seems that the "head" program closes its STDIN, and so terminates the
svn process, so I'm wondering if the potentially long 200.000 rev log
ever gets produced on the server, or if the svnserve process just gets
killed when the pipe and hence the ssh session dies. Does the answer
differ between svn+ssh:// and http:// ?

I'm currently thinking that with "| head -2" it really isn't that
expensive...
