-/**
- * A {@link LockFactory} that wraps another {@link
- * LockFactory} and verifies that each lock obtain/release
- * is "correct" (never results in two processes holding the
- * lock at the same time).  It does this by contacting an
- * external server ({@link LockVerifyServer}) to assert that
- * at most one process holds the lock at a time.  To use
- * this, you should also run {@link LockVerifyServer} on the
- * host & port matching what you pass to the constructor.
