Below test can throughtly check blocking ability of database .lock() method. This feature is one of the most important MUSTS in OCMJD assignment, and it's commonly overlooked by standard tests. This code locks random records, and then creates additional threads, to check two things:
- if .lock() method blocks other threads for locking same record
- if record is not locked, it can be always locked with no problems

If code deadlocks, its simple mean that .lock() method erroneously blocked, when record is not locked by other thread.
