Comment (by gk):

 {{{
 The second one is that shouldLoad is not invoked for redirects. You only
 get one call, for the first URL requested. If you let it pass, it can
 redirect anywhere without you noticing it.

 So, my first guess would be that redirects can bypass this blocking
 mechanism. Did anybody test this?
