OSVRUSTSEC-2020-0111
may_queue's Queue lacks Send/Sync bound for its Send/Sync trait.
Affected versions of may_queue implements Send/Sync for its Queue type without restricting it to Sendable types and Syncable types.
This allows non-Sync types such as Cell to be shared across threads leading to undefined behavior and memory corruption in concurrent programs.
