Abstract
Administration of locks for critical sections of computer programs in a computer that supports a multiplicity of logical partitions that include determining by a thread executing on a virtual processor executing in a time slice on a physical processor whether an expected lock time for a critical section of the thread exceeds a remaining entitlement of the virtual processor in the time slice and deferring acquisition of a lock if the expected lock time exceeds the remaining entitlement.
