Since there can only be one of these, why not have "PendingSeek m_pendingSeek" so it doesn't need to be allocated each time?

Because there needs to be a way to distinguish between "I have a pending seek" and "I have no pending seeks". Otherwise, the ASSERT() in seekTimerFired wouldn't catch when an unexpected seek happened.
