Without the ms argument, the command just prints and returns the current poll-interval time, in milliseconds.
With the ms argument, specify an interval in milliseconds between each polling attempt. The interval can be set from 10 ms to 1 hour.
Remember, the polling interval is a trade-off between the responsiveness of a sleeping agent, and the performance taxing on a target system with a "restless" agent. Remember also, the exact interval will depend on how the target system schedules user-space processes.
This command can be posted on any agent_handle object that is associated with the wanted Simics Agent.
