Feel free to give this branch a go. It switches out the thread for a GCD queue.

Ok, I'll give it a try whenever I get a chance. Took a look at the GCD branch real quick and kind of worried about all the use of dispatch_sync though. I think a better way of managing concurrency is to follow FMDB's style. Assume single-threaded access but providing optional capability to synchronize concurrent access.
Meanwhile by the way, i was able to get a performance speedup of 2x by batching operations together to perform on the address book thread.
[book performAddressBookAction:^(ABAddressBookRef addressBookRef) {
NSArray *people = [book peopleOrderedByUsersPreference];
for (RHPerson *person in people) {
person.firstName;
person.lastName;
person.phoneNumbers;
person.emails;
}
NSTimeInterval taken = [[NSDate date] timeIntervalSinceDate:date];
NSLog(@"rhaddressbook took %f seconds %ld", taken, (long)people.count);
} waitUntilDone:NO];
Logs
