OK, so what is 'Two Phase Locking'?  The term is not explained, and not 
used anywhere else in the manual.  You propose to introduce it here, in 
the tutorial.  I don't know what it means, and I am not really a 
beginner.

'Two Phase Locking' should be explained somewhere, and how it relates 
(or not) to Two-Phase Commit (2PC), don't you agree?
