Abstract

A system, method, computer program product, and carrier are described for to obtaining a decision whether to host an instruction sequence natively in a physical environment in response to an operational history of software apparently containing the instruction sequence or obtaining a decision whether to host an instruction sequence in an emulation environment at least in response to an evaluation of software containing the instruction sequence; and causing another environment to host the instruction sequence in response to the decision whether to host the instruction sequence in the emulation environment or signaling a decision whether to cause an emulation environment to host the instruction sequence in response to the decision whether to host the instruction sequence natively in the physical environment.
