PGL (Program Loader) is a sysmodule designed for encapsulating all program loading logic.
PGL (Program Launcher) is a sysmodule designed for encapsulating all program launching / management logic.
 
The core logic of this sysmodule was previously encapsulated by the ns:dev interface (and the nn.nssrv.ProcessLaunchControlTask thread in particular).

This takes no input and attempts to receive a [[#ProcessEventInfo]] from the observer's message queue.
Every time a process event occurs, pgl receives the event from PM (it does pm:shell->GetProcessEventHandle() during startup and has a thread looping pm:shell->GetProcessEventInfo() to track process events.

PGL sends to all observers' message queues a [[Process_Manager_services#ProcessEventInfo]] for each event it receives, thus allowing for multiple subscribers to process events.
