This is not true at this point:
@mastertype, @master, @rombar @bootIndex and @pciConnectFlags are not
touched here, so you still rely on some clearing beforehand.
This function is clearly meant just to release any allocated memory as
most of our Clear functions.
If you are going to sell it as a full-purposed cleaning functions, you
need to scrub everything.

e.g. this would be misleading, since it is not fully cleared ...

but thankfully fully overwritten ...
Rest looks good though
