Affected versions of this crate unconditionally implement Send/Sync for 'ConVec<T>'. This allows users to insert 'T' that is not Send or not Sync. This allows users to create data races by using non-Send types like 'Arc<Cell<_>>' or 'Rc<_>' as 'T' in 'ConVec<T>'. It is also possible to create data races by using types like 'Cell<_>' or 'RefCell<_>' as 'T' (types that are 'Send' but not 'Sync'). Such data races can lead to memory corruption.
