this isn't necessarily look ahead time, startLeftInput() can be called synchronously:

        if (rhsStartedBefore && isRhsConstant()) // if this is the 2nd+ iteration and the RHS is constant, don't bother restarting right, it will not be used.
        {
            startLeftInput();

should be a head of start, so it includes the whole of start() time afaics.
and normally for convention only: "ActivityTimer s(slaveTimerStats, timeActivities);" i.e. 's' for start.

instead of introducing a new method, can pass (bind) the bool here:

            CAsyncCallStart asyncLeftStart(std::bind(&CInMemJoinBase::startLeftInput, this, true));
