portability fix for test-ssh The __del__ method of sshrepo reads the stderr of the remote process until EOF and prints it. If an exception is raised, this method ends up being called: - on Linux: after the "abort: ..." message is printed - on OS X: before the "abort: ..." message is printed This patch explicitly flushes the stderr of the remote process before raising a RepoError.
