[luabind] Forced garbage collection

[Tom S. <to...@si...>]

    Would there be a way to have luabind force the garbage collection of a
bound object.  I have the code....

    self.my_object = nil
    collectgarbage()

    The assignment to nil does not delete the object, so a collectgarbage()
call is necessary to force the delete.  This is fairly common for lua, but i
was wondering if a policy could be added which forces the GC of the object
on nil assignment?
