RUSTSEC-2020-0111: may_queue: may_queue's Queue lacks Send/Sync bound for its Send/Sync trait.

Description

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.
