    25 // Note that multiple debug agents may attach to a process,

    26 // as the security server will ensure only one is an 'active'

    27 // agent, preventing conflicts. Other agents will be 'passive',

    28 // typically interested only in recording events.

    30 // The above requirement generates the requirement for the class

    31 // to track the agent IDs, as multiple debug agents may be interested

    32 // in a process.
