[ns] questions on error model

["Hong Bin Liao" <hbl@msrchina.research.microsoft.com>]

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).
