Are heap objects never moved by the garbage collector?

[Carl Sturtivant]

"The D Programming Language" (TDPL) p.178 asserts the following.

"The objects themselves stay put, that is their locations in 
memory never change after creation."

I take this to mean that the D garbage collector doesn't move 
live objects and adjust all references to them the way that some 
garbage collectors do. That is to say, the addresses of objects 
are not changed by the garbage collector.

Does D guarantee this?
