[Xcb] Multithreading

[Rayiner Hashem]

Hi. I would just like some information about writing multithreaded 
programs in XCB. I read the papers on XCB, and they talk about XCB 
encouraging a multithreaded programming model. Is there a more detailed 
description of what that model looks like? Should I have one thread that 
does XCBWaitEvent, and distributes events to multiple handler threads 
(maybe one per window), or should multiple handler threads call 
XCBWaitEvent directly?

Thanks in advance!
