add some best practise for this case?

I'm not sure what else we can say here: the best practice we're recommending is to avoid this
situation entirely by ensuring that when a new framework leader is elected, it knows about
(a superset of) all the tasks the previous leader might have launched.

unify the "reconciliation" page with this page, and perhaps move some of the content in the

parts of configuring Mesos to run in HA mode).
