Yep. But regarding the issue discussed, the questions is "when".
AFAIK, the WidgetSet does not create it's ow thread, so the code only
runs when called by the Application (LCL's "interface" code).
Thus only within such a call any handling can happen.
I don't know if the Windowing system creates it's own threads.
I suppose, a kind of queuing always is necessary when transferring
information from one thread to another.
