What qualifies as a tight heap and what qualifies as a significant
increase? Usually when we see OOMEs we increase the allocation by 32MB
and they go away. 

To return to the original question, is it generally better to custom-fit
the RAM allocation (as we currently do) or to unilaterally set all
instances to a higher amount that we know will not generate OOMEs, such
as 512MB?
