This isn’t necessary: replication already runs on a background thread. The 
CBLReplication class just sends messages to the background replicator and 
relays notifications from it, so all CBLReplication methods return immediately.

TL;DR: Just use CBLReplication on the main database; it’s asynchronous and 
won’t block your main thread.

There are a couple problems with the code you showed.
Using CBLReplication inside the background block probably won’t work, basically 
because the background database (`bgdb`) is itself the database instance that 
runs the real replicator work. Trying to predict what would happen is making my 
head hurt; simpler just to say Don’t do that.
The call to `[[NSRunLoop currentRunLoop] run]` will block forever, preventing 
the background database from handling any more requests. Don’t do that either :)
