How many calls per second do you want to execute via the main thread?
QueueAsyncCall is *not* thread safe. If QueueAsyncCall should be made thread
safe, then TApplication must be extended to use a critical section for it (or
some lock-free queue, but since we are talking about the GUI thread, latency is
already so bad, that this makes no difference).
Afaik all PostMessages implementations use a critical section. So you don't need
to do that yourself.
