So far, I've hit only one regression-miss in my code, and I can't seem
to get to the cause of it. Hope someone knows.

I did a query for a non-existant something with a select, and
conceptually it contains a but (should check for error before getting a
row):

	Query q = d_connection.query();
	q << "select id from table where something";
	ResUse result = q.use();

	Row row = result.fetch_row();

	if (result.eof())
	  throw NoResultError(.....);

However, with 2.0.0 (svn: 772) there is no way to find out that the 
query didn't return any results. I would assume that either one
should be true after the q.use():


	q.success() == false

	result.eof() == true

	result.operator bool() == false

Neither of the above is true. Am I missing something?

Also, my compiler was giving warnings about a non-virtual destructor in
lieu of virtual functions inherited from Lockable. Since the virtuals in
Lockable do seem ok to me, I applied the following totally trivial
patch:
