Quite often a virtual object does not change from one guard to the next.

-\cfbolz{store sinking}
+Similarly, stores into the heap are delayed as long as possible.
+This can make it necessary to perform these delayed stores

+of the delayed stores to be able to perform them when the guard fails.
+So far no special compression is done with this information.
