   I don't have a "model". I just tried to describe what the LCL does.


You can see the multiple Queues in the source code:

  - Queue in the fpc RTL that is fed by things like "TThread.Queue"
  - Queue in the Linux GUI based LCL that is fed by events (such as Key 
or Mouse) generated by the WidgetSet it _attaches_ to  (this defines is 
the "attach" word that I mentioned)
  - Queue in the Windows OS the LCL in a Windows based Widget type 
attaches to (instead of implementing it's own event queue)
