kill(pid_of_ssh, SIGKILL) is rude

When using the svn+ssh access method, svn kills the ssh process with
SIGKILL (a.k.a "kill -9"). This doesn't give ssh (or a wrapper invoked
via the SVN_SSH environment variable) a chance to clean up. I had
hundreds of temporary files lying around before I figured out why my
wrapper wasn't deleting its temporary files: svn was rudely killing it!

I see the comments in the source about why svn does this. I suspect
that the real problem could be solved by a strategy like this:

    wait a few seconds to see whether ssh exits by itself
    if not, then kill(pid_of_ssh, SIGTERM)
    wait a few more seconds to see whether ssh exits by itself
    if not, then kill(pid_of_ssh, SIGKILL)
