Unfortunately GetInheritanceSourceW seems particularly expensive.
On my test number of system calls:
GetInheritanceSourceW: 409
GetNamedSecurityInfoW: 17
SetNamedSecurityInfoW: 27

So my plan is to count the number of object inherit ACEs in the parent DACL andthe number of inherited ACEs in the moved file and call SetNamedSecurityInfoW if they don't match.
