There was a problem hiding this comment.
I agree this is a safer approach than what is currently merged, but as mentioned in thread, this is somewhat moot with #465 since in that approach we spin up separate goroutines to call update() and therefore don't deadlock.

update()might lockmuwhen it callsgetTargets(). Which would deadlock. Instead, let's make it much narrower in scope and just copyresolvers.
