I couldn't have described it better.

handleEvents() returns 1 if any UI events came in (or if the event  
buffer is not empty), otherwise 0 to indicate no UI activity to worry  
about.

In other words, ioRelinquishProc only sleeps if there is no UI  
activity and no descriptor is ready for a pending i/o operation.

Would this be particularly helpful to you?  I never call aioPoll()  
with non-zero from anywhere except relinquishProc, so for me it's  
better being outside aioPoll.  But if you'd find it useful inside  
aioPoll then I don't think moving it there would break anything.
