Although the clock won't run out for two more weeks, I'm putting SRFI 124
into last call.  I've fixed the bugs in the Racket implementation (I hope),
added more references from the mailing list, cleaned up the implementation
sections.  I have *not* added Riastradh's proposed fence instruction,
since it is not found in any existing version of ephemerons.  If someone
wants to argue the case, go for it.

Arthur, please push <http://www.ccil.org/~cowan/temp/srfi-124.html> to
the repo.  Thanks.

Monday we watch-a Firefly's house, but he no come out.  He wasn't home.
Tuesday we go to the ball game, but he fool us.  He no show up.  Wednesday he
go to the ball game, and we fool him.  We no show up.  Thursday was a
double-header.  Nobody show up.  Friday it rained all day.  There was no ball
game, so we stayed home and we listened to it on-a the radio.  --Chicolini
