I don't know what sort of application you want this for, but in 
principle it sounds very much like a typical game loop. Using a separate 
thread for constant update isn't likely not a good strategy. This 
article describes how to separate logic UPS (updates per second) from 
rendering FPS (frames per second):

Following that technique, you should be able to keep your 1000hz loop 
and have your 60hz display updates all in one thread.
