User space need not be the user. Currently user space doesn't tell
the kernel how much functionality it needs. open/close give a binary
opposition which badly maps onto the graduated capabilities devices
have.

For example do you really need every key pressed while the screen saver
is running or is it enough for the keyboard to be able to generate a wakeup
event?
