[Click] please_stop_driver() function

[Andreas Tarp]

Hi,

i have a question regarding to the please_stop_driver()  function from 
click/router.hh:

I think in theory the line

router -> please_stop_driver()

somewhere within an element (for example in the Element::simple_action 
part) should stop the runnig click configuration and return to the linux 
console.

In my case click quits when calling these function, but I always receive 
a SIGSEGV error. Do I have to pay attention to some other rules, when 
calling please_stop_driver() ?

My intention is to write a small element, which quits the running click 
router, if a packet is passed to the element.

Thanks a lot,

Andreas
