1. A method for providing serialization support for a computer system resource which includes processes requiring serialization, the method including: commencing one of the processes requiring serialization; creating a representation of the process, the representation including a serialization token for the process; providing the representation on a medium accessible by all components of the computer system to which the serialization requirement applies; deleting the representation when the process is complete; on commencement of a further one of the processes requiring serialization, checking for the existence of the representation on said accessible medium and, if said representation check is positive, controlling serialization of said processes with reference to the serialization token.
