Oops. Indeed. TASK_RUNNING isn't a bit at all, it's a lack of sleep.

Turning the logic the other way around:

	/* Ignore processes that are dead or stopped (except for SIGKILL) */
	mask = TASK_ZOMBIE | TASK_DEAD;
	if (sig != SIGKILL)
		mask != TASK_STOPPED;

and testing for !((p)->state & mask) should fix it. The mask ends up being 
the states that are _not_ good to send signals for ;)
