Hello All,
I have moved the nightly tarball generation to start at 9pm US eastern time.
At current tarball creation times, it is safe to grab fresh tarballs by 10:30pm
assuming we have no more than three (trunk, v1.1, v1.2) that are queued for
generation. If you want to live on the edge, they currently take about 23-25
minutes each to make...

Happy thanksgiving!

P.S. - If anyone would care to investigate a way to improve the tar build time,
please take a look at the contrib/nightly/create_tarball.sh script
which is in the trunk's SVN that is used to perform this nightly ritual.
The bulk of the time is spent in these three commands:
  autogen.sh
  configure
  make -j 4 distcheck
But there is some inefficiency afterwards in the generation of the
md5sum & sha1sum, since it recomputes them for each tarfile found
in the destination directory (the web dowload page), not just for the new
tarfile.
