I did some more searching on the net and I got one thread where this
was discussed ..

think I understand what the issue, good we got to know of it before we
made design based on this  -;)

anyways, my other questions are still there . 
if I understand correctly, 
reset command on ixp425 is basically then start execution from 0x0 again ?

and sleep etc are spin locks, checking timer register in a while loop
? pressing control C makes a interrupt and u catch it to stop flow,
rather come out of flow ?
