Andreas Kling 9ed272ce98 Kernel: Disable interrupts while setting up a thread blocker 
There was a race window between instantiating a WaitQueueBlocker and
setting the thread state to Blocked. If a thread was preempted between
those steps, someone else might try to wake the wait queue and find an
unblocked thread in a wait queue, which is not sane.
