ok taking a 5k pop province

0% taxation will undo around 35 unrest approx, i think.
patrolling instead of having 0% tax will kill 10 pop per % unrest, so around 350 pop :O (i'm not sure if this goes down at all for smaller pop provinces)
death 3 will kill 30 pop
getting 13 bloodslaves a turn (guestimate as to average) will kill 26 pop.

so death 3 and 0% tax bloodhunting will kill around 55-60 pop/turn, letting one bloodhunt in the province for 30+ turns (since numbers lost to death will decrease as the pop decreases) before pop goes to 3K (which is still ok for bloodhunting, just not as good)

while growth 3 and 100% tax w/ patrollers for the unrest will kill over 300 pop a turn, letting one bloodhunt w/ similar effectiveness for about 8 turns tops...

summary: patrolling is murder.

and we see that Graeme's estimate of 1000 dead a turn from massively patrolling away the unrest from keeping taxation at 100% and bloodhunting w/ 10 hunters is, if anything, on the low side. besides being especially silly, since the massive patrolled-away unrest still affects your tax take.
