I've just noticed that SDL has just had a simalar fix listed on the SDL
From reading it it looks like the issue is due to the continue statment
after (ret == -EAGAIN) which means it busy loops until it can write. The
solution they list is to nanosleep.
But if we're going to loop until we can write why not use blocking
writes? Or use select with non-blocking?
Anyway just a suggestion if it's any help, from a allegro-dev lurker
