RE: [ns] issues on ErrorModel AGAIN!

I am not sure why there is a delay before notifying the packet
corruption to the module called the error model. 

But, corrupted packets are immediately sent to the specified target
 (which is a neigbor node's link layer or the next low layer in wireless networks)
 without any delay after scheduing the notification event with some arbitrary
delay.

You can see this flow by using a gdb debugger.

Hi, Folks
	I sent the following letter several days before. I got no answer
for it. IMHO, it's very fatal issue on the correctness of model of the
systems. Could anyone give me answer of it?

Hi, folks
	after reading the source code of errmodel.cc, I wonder why the
resume handler should be delayed for a random period between 0 to
(PacketSize/BW). why not this packet with error is delayed for a period
(PacketSize/BW)?
	The former cause more burst error when error unit is bit, byte
or time (in two/multi state error model).
