patch 8.1.0834: GUI may wait too long before dealing with messages

patch 8.1.0834: GUI may wait too long before dealing with messages
Problem: GUI may wait too long before dealing with messages. Returning
early may cause a mapping to time out.
Solution: Use the waiting loop from Unix also for the GUI.
(closes #3817, closes #3824)
