Well, delayRead() and the stuff it calls stands for 493.8MB. 201MB of those
do indeed go to close callbacks.

This was a few hours. And yes, it seems to run pretty linearly.

I'm not entirely sure what stats you're looking for. Almost all of the
overconsumption in the pools (300MB or so) originates in delayRead(), though.
