        This method is called when the plugin wont be used anymore and is used

        Example where a persistent SSI can be found:

        Say you have a "guestbook" (a CGI application that allows visitors
        to leave messages for everyone to see) on a server that has SSI
        enabled. Most such guestbooks around the Net actually allow visitors
        to enter HTML code as part of their comments. Now, what happens if a
        malicious visitor decides to do some damage by entering the following:

        <!--#exec cmd="ls" -->

        If the guestbook CGI program was designed carefully, to strip SSI
        commands from the input, then there is no problem. But, if it was not,
        there exists the potential for a major headache!

class CachedQueue(Queue.Queue, QueueSpeedMeasurement):
    """
    The framework uses the producer / consumer design pattern extensively.
    In order to avoid high memory usage in the queues connecting the different
    parts of the framework we defined a max size.

    When a queue max size is reached, one or more threads will block. This
    line is printed during a real scan:

        Thread blocked 5.76617312431 seconds waiting for Queue.put() to have space
        in the Grep queue. The queue's maxsize is 20.

    In the case of the Grep consumer / producer the problem with a block is increased
    by the fact that HTTP responses won't reach other parts of the framework
    until the queue has space.

    Increasing the queue size would increase memory usage.

    Using an on-disk queue would increase CPU (serialization) and disk IO.

    The CacheQueue is a mix of in-memory and on-disk queue. The first N items
    are stored in memory, when more items are put() we just write them to
    disk.

    The CacheQueue object implements these methods from QueueSpeedMeasurement:
        * get_input_rpm
        * get_output_rpm

    Which allows users to understand how fast a queue is moving.
