As we have already written in some previous mails to there is a

Could you elaborate on this ? Is this "triggering" done by some kind
of self-piping or using an OS semaphore ? Is it provided for all OSes
and Archs
Or do you mean a function call is provided that allows the user (or
the LCL) to implement such a functionality.
The latter:
http://www.freepascal.org/docs-html/rtl/classes/wakemainthread.html
It is called by the internal procedure ThreadQueueAppend which is used
by both TThread.Queue and TThread.Synchronize. Additionally if the the
main thread is already waiting inside a CheckSynchronize() call it is
notified using an event.
