Oh, another thing is to check if any of that is from mmap-ed
files or if its all anon heap memory.  The SQLite I'm using
from Debian doesn't seem to mmap files (I've never had to look
too hard at tuning SQLite) and I don't think libxapian uses mmap
at all either (just pread).  But LKML's sqlite files are huge.

I know git(1) will mmap entire packs into memory.  If/when
public-inbox start supporting Git::Raw (libgit2) or even
Cache::FastMmap, then yeah; process sizes will look a lot
bigger.
