I got it, in WebTrafSession::handle(), the code was like this:

        TimerHandler::handle(e);
        // If I've scheduled all my pages, don't schedule it any more.
        if (++curPage_ >= nPage_)
                return;
	sched(...);

so it calls handle() -> expire() first, then increase the value
of curPage_, and since in expire(), the program will increase
the value of donePage_, then check if donePage_ >= nPage_, and
will stop there if it does. (so it could be the case that curPage is
less than donePage_ when all the page are launched).

Therefore, it leads to the warning and abort sequence when session
ended because curPage_ != donePage_.

Exchanging the order of TimerHandler::handle(e) and ++curPage_
will solve this problem.

I was wrong in that I thought sched() would launch a page, sorry for
previous misleading messages.
