If you are bored this weekend, you can take a look at the table locks doc,
that I attached at HBASE-7305.
There has been a lot of confusion about the current status, design and
implementation, for which I take the blame.
Hope these notes help to answer the questions. If not, leave a note here,
and I'll update the doc to incorporate the answer.
