Organization: the aerie

This is an update on the problems using 'screen' with the
latest snapshots.

The problem I reported where the display does not update
properly started with a change in select.cc. If I revert
that change with the patch below, that problem goes away.

But then, the 'screen' processes don't die when 'screen'
terminates.
