    A heappool 1 element is leaked when a thread other than one of
    the initial worker threads is created, goes native to do a
    ORB_init and then ends.
    The heappool 1 element being leaked is for TCB objects. A TCB
    object has 3 pointers. The 3 pointers are TCB pointer,
    STCB pointer and BTCB pointer.
