Re: Potential regression: high server-side memory consumption during import

per-connection state at present.

Please excuse the interjection here: My eyes spied "per connection" and I
wondered if something I'm doing elsewhere that is closer (but not exactly)
"per user" might help in terms of thinking.

I've a server-side 'wrapper' around Svn that's calculating authz
permutations for each *user*. That transcends any sessions and connections
for the user. Two users in the same groups(s) with no other variance in
authz config will use the same cached Svn entries everywhere. I've speedy
unit tests too for it, but I've a ways to go because of the exclude grammar
of authz's little language.

If the thing works well enough, but eats too much of the
disk-backed-ram-cache <http://www.mapdb.org/> I'm using, I could extend it
to do the same per directory. Because right now it is effectively a 'from
root of repo' determination for a user.

Of course, you don't want the code I've done because it is not compatible
with the current Svn toolchain. I'm thinking about a Rust rewrite, but
that's a year away, even if it was compatible with the way Subversion is
today.
