- * Known bugs:
- *  - sometimes messes up the IP stack
- *  - any manipulations besides the few operations described in the README, are
- *    untested and likely to crash the system
- *  - should lock the flow while there is data in the queue (?)

-
-	-----------------------------------------------------------------------
-
-	Algorithm skeleton was taken from NS simulator cbq.cc.
-	If someone wants to check this code against the LBL version,
-	he should take into account that ONLY the skeleton was borrowed,
-	the implementation is different. Particularly:
-
-	--- The WRR algorithm is different. Our version looks more
-	reasonable (I hope) and works when quanta are allowed to be
-	less than MTU, which is always the case when real time classes
-	have small rates. Note, that the statement of [3] is
-	incomplete, delay may actually be estimated even if class
-	per-round allotment is less than MTU. Namely, if per-round
-	allotment is W*r_i, and r_1+...+r_k = r < 1
-
-	delay_i <= ([MTU/(W*r_i)]*W*r + W*r + k*MTU)/B
-
-	In the worst case we have IntServ estimate with D = W*r+k*MTU
-	and C = MTU*r. The proof (if correct at all) is trivial.
-
-
-	--- It seems that cbq-2.0 is not very accurate. At least, I cannot
-	interpret some places, which look like wrong translations
-	from NS. Anyone is advised to find these differences
-	and explain to me, why I am wrong 8).
-
-	--- Linux has no EOI event, so that we cannot estimate true class
-	idle time. Workaround is to consider the next dequeue event
