--- Comment #48 from Tor Lillqvist <tml at iki.fi> ---
In fact, the documentation for the Win32 PeekMessage()
https://msdn.microsoft.com/en-us/library/windows/desktop/ms644943(v=vs.85).aspx
does describe that it is not as trivial as one might hope. "During this call,
the system delivers pending, nonqueued messages, that is, messages sent to
windows owned by the calling thread using the SendMessage, SendMessageCallback,
SendMessageTimeout, or SendNotifyMessage function. Then the first queued
message that matches the specified filter is retrieved. The system may also
process internal events."

And about SendMessage(), "The SendMessage function calls the window procedure
for the specified window and does not return until the window procedure has
processed the message".
