===================================
These are runs of my solution program.
There is synchronization. The messages
are printed in an order consistent with
the star being formed according to
a correct sequence.
The program does not have the same
output each time it is run, because
many things happen 'by chance' depending
on which thread the scheduler chooses to
run, and when. (Also, this version of the
program has its own programmed random
delays.)
However, the execution of the protocol
assures that the outputs are always
correct - assuming there are no bugs
- none are known at this time.
