    Increase the waiting period to receive a port creation event

    This patchs increases to 15 seconds the timeout to wait for a
    port creation event in ``WaitForPortCreateEvent``. This patch is also
    adding the update "event" to the tracked events, just in case if the
    "create" event has been ignored before.
