Consider the timestamp-ordering protocol, and two transactions, one that
writes two data items p and q, and another that reads the same two data items. Give a schedule whereby the timestamp test for a write operation fails and
causes the first transaction to be restarted, in turn causing a cascading abort
of the other transaction. Show how this could result in starvation of both transactions.
(Such a situation, where two or more processes carry out actions, but
are unable to complete their task because of interaction with the other processes,
is called a livelock.)
