[Ecls-list] ECL HEAD + Slime HEAD

[Tobias C. Rittweiler]

I'd like people to test current Slime HEAD with ECL HEAD.

If you build ECL with --enable-threads, Slime will now use threads on
ECL. If you build ecl with serve-event, Slime will use that (though I
haven't tested that yet.)

All in all, this should result in much better user experience. No random
hangups anymore, etc.

Important is that you do use ECL HEAD though, revisions of a few days
ago, won't do.
