 operations.

 First, I'd like to clarify my position: I'm not necessarily pushing
 the idea of using the boost framework.  I'm just trying to show
 various possible options.

 Then, about this specific point: are you saying this by actually
 checking the code or the behavior of the boost file lock?  I used the
 term "RAII" as an idiom, which in this context means "locked" status
 is the resource and it will be automatically unlocked when the
 corresponding object is destructed, rather than the resource
 acquisition in its literal sense.  It doesn't automatically mean
 opening the file.
