Why?  Is there some compelling underlying reason they can't make use
of all those desktop cycles like other massively multiplayer games do?

What language?  Some ad-hoc thing of their own?

Well, sure, I think that's been done, although I don't know if
anyone's using it for real in a production setting.  Here are a few
links to related subjects - tcc, CriTcl, and LuaJIT:

  http://fabrice.bellard.free.fr/tcc/
  http://wiki.tcl.tk/2523
  http://luajit.luaforge.net/luajit.html

But why would you think that just-in-time compilation of C or the like
would be central in fixing Second Life's performance problems, rather
than just doing a better job of software engineering in general?

I know nothing about Second Life, but from your description, if
they're looking to change programming languages, Erlang (or something
like it) might be the best fit.
