    Summary: Data races in unicycle

    Details: Affected versions of this crate unconditionally implemented `Send` & `Sync` for types `PinSlab<T>` & `Unordered<T, S>`. This allows sending non-Send types to other threads and concurrently accessing non-Sync types from multiple threads. This can result in a data race & memory corruption when types that provide internal mutability without synchronization are contained within `PinSlab<T>` or `Unordered<T, S>` and accessed concurrently from multiple threads. The flaw was corrected in commits 92f40b4 & 6a6c367 by adding trait bound `T: Send` to `Send` impls for `PinSlab<T>` & `Unordered<T, S>` and adding `T: Sync` to `Sync` impls for `PinSlab<T>` & `Unordered<T, S>`.
