We need to implement a timeout for some (Mac/iOS) code that reads from a socket via a CFReadStream

Are you using CFSocketStream is sync/blocking mode? That’s supported, but quite unusual (most folks use CFSocketStream async via the NSStream delegate mechanism or the CFStream client callback). This matters because, for example, `SO_RCVTIMEO` is only relevant in blocking mode.
