1. A method, comprising: issuing one or more thread control signals to a sequencer that is sequestered from an operating system (OS), wherein said issuing is performed by an abstraction emulation layer in response to a user-generated instruction; and performing a set of operations to cause suspension of execution on the sequestered sequencer; wherein said set of operations are performed by the abstraction layer in response to a ring transition on an OS-visible sequencer and wherein said set of operations further include issuing said one or more control signals, wherein said control signals include a signal to place the sequestered sequencer into a wait state.
