// At the present time, VBU runs hostboot without a Simics

// clock cycles as it looks for a runnable task. When the sleep time expires,
// the calling task will resume running.
//
// In the future there could be a Simics front end to hostboot VBU. Then
// a possible implementation will be to use the Simics magic instruction
// to trigger a Simics hap. The Simics hap handler can call the simdispatcher
// client/server API to tell the Awan to advance some number of cycles.
