In order to avoid problems with the incremental marker you could ensure that a
GC is completed immediately before doing the replacement.  See the code in
HeapSnapshotsCollection::FindHeapObjectById for an example.

LGTM

Thank you for advice.

Actually I'm fine with patching dead objects amongst others. Is it the only
thing I should be caring about? In this case probably it's not required to do
extra GC.
