mooix is not terribly high-performance, and the machine it's
currently running on is fully encrypted, which Doesn't Help (tm).

Here are some notes and ideas about how to make things better:

Improvement Suggestions

Faster hybrid daddy: have markers like Eimi's untagged special in
the main source tree; users can insert them themselves if they want,
but they don't have too, but not having to go all they way up the
tree saves time.

session, $avatar, $direct_object and $this flags (and any
similar things that may exist) are not shortcutted in msg.c; that
is, propigate is run all the way through, even though (presumably)
finding the targets for a message with those flags requires no
propigation. I suspect this to be fairly serious.

Performance suggestion: Per-user flag to select from the following:

1. Daddy Tag

2. Own language always.

3. Daddy Tag with own language.

1. 2 being much, much cheaper.

There must be *something* that can be done to make nearbyobjs
faster. Caching it and watching for changes is one possibility;
test mod time on the location's contents? Enh.

Rather larger scale idea:

We could have a layer in the language bindings that caches results
for 1 second (unless told not to).

Dunno if this would be faster than a RAM disk on a real box.

Might be better done on the parser; probably the most savings there.
