[Haskell-cafe] What magic has the new IO manager done to improve performance ?

[yi huang]

I' m curious about the design and trade offs behind the new IO manager. I
see two changes from the code:

1. Run IO manager thread on each capability.
2. Use ONESHOT flag to save a system call.

Is there other interesting things to know?
Is it possible to use epoll's ET mode to save even more system calls?
