=== GetEventHandle ===
This takes no input and returns an output copy event handle.
=== GetEventInfo ===
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 [[#ProcessEventInfo]] for each event it receives, thus allowing for multiple subscribers to process events.
