So the proximate cause of the crash is that {{evolve}} does an unnecessary
bidirectional serialization. For large messages this causes 2 unnecessary large
allocations even if is doesn't trigger the {{CHECK}}.

> Project: Mesos
> Issue Type: Bug
> Components: HTTP API
> Reporter: James Peach
> Priority: Critical
>
> The master can crash when generating large responses to small API requests.
> One manifestation of this is querying the tasks.
