errno_t	err
	Error number set when unblocking the thread, `EOK` for no error.

clock_t	deadline
	Deadline for timeout, `CLOCKS_NEVER` for no timeout.

wait_cpu_ctx_t *	cpu
	The wait cpu context of the cpu the thread is blocked on.

Detailed Description

Per-thread wait context.

Each thread stores all wait queues it is currently waiting on in here to allow blocking on multiple wait queues, since if one queue unblocks the thread must be removed from all other queues as well.
