i added some in-process data collection to ktistec in order to better understand how it uses memory.

the chart shows the accumulated total requested memory (blue) over time. as expected, it grows monotonically and almost linearly. in theory, i guess, if i posted something engaging, you'd see the effect of the engagement  (likes, shares, follows, etc. etc. etc.) on memory usage. in any case, the heap (red) remains flat.

i think it would be great to have this chart on the metrics page. when time permits, i'll add it. in the meantime, if you're running a (very) recent build, you're collecting data.

shoutout to @rahul btw for pointing out the memory problems (now fixed, i hope) that led to this work!

Thanks @toddsundsted, I _really_ appreciate all the work you are putting into Ktistec! I should be able to verify the memory problem on Monday, when I have access to a build machine.
