Library cleanup

[Victor Porton <porton@narod.ru>]

I am writing bindings for a C library which requires both initialization and 
cleanup:

[[[
raptor_init()
raptor_finish()

Initialise and cleanup the library. These must be called before any raptor 
class such as raptor_parser, raptor_uri is created or used. Note: as of 
1.4.19 these are wrappers around a static instance of the new raptor_world 
class. In Raptor 2.0 this initialisation and cleanup method will be removed.
]]]

Initialization is clear: I just put it into the handled sequence of 
statements of the package (should I also add Elaborate and/or Elaborate_Body 
pragma?)

But how to do cleanup? That is, where to call raptor_finish()?

One way is to create a Limited_Controlled object in the package. Is there a 
simpler way?
