Although the patch is still under test, a new task proposal comes to
my mind.


A new task: lock underlying objects of struct file, namely a vnode, a
socket, a pipe, a fifo and an event queue.


A socket and a pipe is not mpsafe for now.

A vnode (and a fifo) has an interlock, so it might already be mpsafe.

An event queue is... up to jlemon?
