I remember talking about this with Alex.
He wanted to add some functions to the GC and this is what I came up 
with based on the current implementation.
It uses the synchronized GC.addrOf to check whether the loaded pointer 
is still valid. Still looks correctly synchronized to me.

In fact the load!(msync.acq) could be made load!(msync.raw) too.
