[Click] Click router: routertask

[Andrushka]

Hello!
First of all sorry for my English.

I want ask one question.
Routertask's created in master.cc in Master::Master(int nthreads)
_threads.push_back(new RouterThread(this, tid));

I want to run test.click config.

i do:
router->master()->thread(0)->driver();

All goes well.
I see have called Task::call_hook() for InfiniteSource.

But _next for InfiniteSource point to routertask;

Why ?????
Why he doesn't point to Strip element ???

Same things if i turn on
#define HAVE_STRIDE_SCHED 1
#define HAVE_TASK_HEAP 1
(runing only InfiniteSource element).

I can't find place where CLICK build sequence of task for scheduling.

Please help!
