In fact Delphi implements TThread.Queue. while Lazarus/FPC currently don't.

The LCL provides Application.QueueAsyncCall.

Both procedures are supposed to perform the same action. But

(1) Application.QueueAsyncCall is not a TThread class Function and thus 
does not need support from the RTL (thus the FPC team) and
(2) Application.QueueAsyncCall is is more versatile, as it additionally 
to the Procedure itself and the self pointer, it also provides a 
parameter (pointer) to the procedure to be executed by the main thread.
