This is similar to example, but it illustrates the use of the coordinator
database.
To demonstrate, do: make check [Checkpoints every 5 seconds]
After killing it, try: ./dmtcp_restart_script.sh
This uses the database service of DMTCP. At checkpoint or restart time,
each process can install a key-value pair, and then optionally query a value
for a given key. This type of facility can be used internally by DMTCP
for such things as registering an old_pid/new_pid pair at restart time,
and then querying the new_pid of a remote process given its old_pid.
