De-queuing Windows messages and X events happens in the same thread of execution. Draining the windows message queue can lead to the X event queue overflowing if lots of those windows messages cause X events (e.g. if a keyboard macro program has just dumped thousands of keypresses into the Windows message queue). See the mailing list thread [1] for more details. Processing one Windows message per wakeup, rather than all of them gives the X server a chance to do stuff as well after each message.
