That's a comment that I added just recently under a
slight misapprehension. Once we've figured out what
the right thing is we can fix it, or make the code do
what the comment says.

The actual current situation is "this function does nothing
to ensure the RAMBlock is correctly migrated, so if you
do nothing then you'll wind up with migration being silently
broken, if more than one thing is doing this at once in
the system, but if one and only one RAMblock is in this
situation then it'll work by luck". Which is definitely not
behaviour we are doing on purpose :-)
