 // The global class which tracks all debugged processes.

 // 

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

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

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

 // typically interested only in recording events.

 //

 // The above requirement generates the requirement for the class

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

 // in a process.
