Well, the main thread sends commands to the render thread using the primitives in src/lib/evas/common/evas_thread_render.c for each canvas. The render thread has the code in that same file and wakes up as soon as a canvas has completed its list of commands for that frame and issues the final flush command. The render thread takes the list and starts issuing the callbacks and when it reaches the flush command it sends an async event to the main thread so it completes some steps like cleaning up data structures, issuing post render callbacks, for the sw_x11 it calls a function passed to evas_render_async() to update the regions in X, updates the cur for the objects and so on. Thus, if you see a stall then it *might* be that something is delaying the async event to the main thread to actually be sent or be received and processed. If you need any more insight on the code, just let me know.
