As I said, I already did try this some years ago Trying both to 
implement a new event queue mechanism (stolen from mse), and - better 
idea - reusing the event queue code from the "GTK" WidgetType. But I 
gave up after some weeks (not fulltime, of course)  due to the enormous 
complexity of the Lazarus units involved.

In fact I did only take a look  at the Lazarus units, not the RTL, at 
that time not knowing that it would need to be revised, too.

A major political problem is that - to do it right - all WidgetType 
units that are dealing with the EventQueue would need to be modified (e. 
g. using the new RTL interface and moving QueueAsncCall out), and of 
course the basic work needs to be done in the RTL (e. g providing the 
"SignalMainThread" interface with an EventQueue that is to  be used for 
non-GUI events (and be merged with the GUI events from the LCL at the 
queue input (GTK and many others) or the queue output (Windows) and 
moving QueueAsncCall in).

This would need a huge testing effort to guarantee  that existing code 
would not be broken.

All this can't be done by a one-man team of volunteers.

As always, I feel that before trying any start on this, a rather 
commonly agreed concept would need to be decided upon.
