In the light of morning it occurs to me that probably the best code
factoring for this is for dependency.c to export a
performMultipleDeletions() function that takes an objectAddresses list
of targets and does all the dependency-chasing internally. This would
reduce the amount of cruft that has to be exported from dependency.c.

Other than that, the patch looks plausible in a very fast scan.
