Oh, for crying out loud.

It's related in the sense that it's a leak, and any leak will tend to
run the system out of memory more easily, but what I observed was a
large leak into MessageContext, and that would be a leak into
CacheMemoryContext, so I think it's probably a sideshow rather than
the main event.
