Supporting Lock-Free Composition of Concurrent Data Objects: Moving Data between Containers

Daniel Cederman, Philippas Tsigas
2013 IEEE transactions on computers  
This move operation allows data to be transferred from one container to another, in a lock-free way, without blocking any of the operations supported by the original container.  ...  They have also been shown to work well in practice.  ...  Requirement 2) There is nothing shared between instances of the object, so the insert and remove operations can succeed simultaneously.  ...
