Subject: Assn1 clarifications

(This message is being sent to all CPSC 826 students)

I apologize for the imprecision of this assignment (and
its alleged clarifications).

It has been pointed out that it is actually necessary
to send <<4>> pings per "cycle" ... namely short and
long to both H1 and H2.

Thus you may assume that the number of pings sent will
always be divisible by 4.  Thus if the number specified
is 20 you should send:

   Short to H1
   Long  to H1
   Short to H2
   Long  to H2
   :
   Short to H1
   Long  to H1
   Short to H2
   Long  to H2

until a TOTAL of 20 pings have been sent.
