The question is; what should we replace it with. Personally I'm more of a fan of intrusive reference counting for VCL

ref-count those guys anyway I think. Then again rtl::Reference<Foo> lost its nasty virtual methods recently (IIRC), so
- perhaps we could use that - but for the fact that it's unpleasantly long to type.
SvRef (include/tools/ref.hxx) is the rough equivalent of boost::intrusive_ptr,
so that would be my suggestion.
It use no atomics and has only one extra virtual call(other than the actual destructor) but removing that is
straightforward, I just haven't got around to it.
Otherwise we should just standardise on boost::intrusive_ptr and remove SvRef.
I'd also love to avoid 'orrible casts everywhere when converting to references to parent types [ perhaps I just do
this wrong myself ;-]
This should be fixable if it doesn't already work - myself and sberg already
did this for rtl::Reference.
I guess we need to have a plan in-place there before shunting all those widgets off onto the heap where we can
lifecycle manage them sensibly =) Thoughts ? Michael.
Mostly I guess we need to figure out where and when to destroy them - is it in the destructor, or in some other method
specific to this task?
