===================================
This a run of my solution program.
It uses semaphores to synchronize
the threads. In this run, we see
that the various threads appear to
process the data in the correct order.
Naturally one should not expect the
program to have the same
output each time it is run, because
many things happen 'by chance' depending
on the random delays and how the threads
are scheduled.)
