Because I was thinking that calling WAIT FOR LSN before
BEGIN ISOLATION LEVEL ... is equivalent to calling it after, since the
transaction snapshot is not taken until the first SELECT. However, I can
see how requiring that order could be problematic, especially when the
driver issues BEGIN ISOLATION LEVEL ... automatically.
