Hi s7r, I can't answer most of your questions offhand, but this may
have something useful:
It's a bug I opened about the setting on low-memory machines.
s7r at sky-ip.org:

- From the above bug, I know the early minimum was 500MB. I do not know
if or how the default was calculated. It should now be 384MB in Tor
0.2.5.x so that relays with ~512MB of physical RAM can function (e.g.
Raspberry Pi and other little ARM boards, and doorstop Pentiums, etc.)

It is my understanding, which may be incorrect, that once this feature
- - or more accurately its immediate predecessor discussed in the bug
above - was introduced, that it was turned on by default.
Hope this is helpful.
