(and supposedly for Application.QueueAsyncCall)

Of course I do know this and this is what makes it impossible to port 
the Delphi applications, my colleagues did, to a non-GUI environment.

The new idea now is, that implementing PostMessage (and supposedly 
Application.QueueAsyncCall) might be done using the existing RTL Event 
queue (which only recently came to my full awareness), instead of 
creating (or in Windows  attaching to) an additional queuing mechanism.

What non-GUI events - additionally to the events I mentioned - would be 
needed for "the whole event system of the LCL" ?

Of course I do know that this is doable (and I already did it several 
times). But (as I mentioned multiple times) I don't need this for any 
concrete application, but for creating an "SDK" that allows for porting 
existing Delphi applications in a way as easy to use as possible. Thus 
an "Application" and "Postmessage" (thus an LCL Widget Type 
implementation) is necessary.
