// Tricks the registration code to believe that PartitionAlloc was not already
// registered. This allows a future library load to register PartitionAlloc's
// zone as well, rather than bailing out.
//
// This is mutually exclusive with EarlyMallocZoneRegistration(), and should
// ideally be removed. Indeed, by allowing two zones to be registered, we still
// end up with a split heap, and more memory usage.
//
// This is a hack for https://crbug.com/1274236.
