[Changes for 0.29 - 2008-12-13]

* Publisher and index fixes

* We don't need to force select_timeout anymore, and it causes
  explosions if called during global destruction, when $$self->[0]
  (_part_ of the pseudohash) may have gone missing already, but the
  object itself is still there.  So $$self->{anything} explodes with
  "not a hash reference" _sometimes_, despite $$self always being an
  ..friends don't let friends use pseudohashes.
