Sorry.  To back up a little:

squid version: 3.4.8-6+deb8u1 (debian jessie)

With that config, I see memory hits to the cache, working fine. 
However, if I try to download something that's a couple of MB, it never
writes to either cache directory.

I get this in the store.log:

...and this in the access.log:

On a second hit, I get the same thing, RELEASE and TCP_MISS.

Hah, no.  The goal is to cache the most popular RPM and Debian packages
and to spread the load out geographically.  Most of them are somewhere
between 20-300MB. Unfortunately, right now it seems to only cache what
fits in memory.

Also, sorry, just noticed this after I'd already reply-all'd:

I won't do it again...  :/
