So the strategy here is the UnwindTable class calls its `Initialize()` any time a client wants to use an UnwindTable so that it can be lazily filled.   Then Module calls `UnwindTable::Update()` any time something gets added to the module that might change the unwind table.

That seems pretty clear.  

It is a little odd that the laziness of the UnwindTable itself gets defeated by Update, which forces the Initialize even if the unwind table isn't currently being requested.

Not sure if that matters?  If it does, Update could just tell the UnwindTable that next time it gets asked a question it has to reread the unwind information.  Maybe it could even just set m_initialized back to `false` and  then let the lazy initialization redo the work when requested?
