informative_rescue.rb

#!/usr/bin/env ruby
require 'rubygems'
require 'logger'

logger = Logger.new($stdout)

begin
  # let's do something that will never exit 
  # and then we can watch this not die unless we use kill -9
  while 2 > 1
    logger.info "this is never going to exit!!!"
    sleep 1
  end
rescue Exception => e
  logger.info e.inspect
end

Seems like this got fixed in Ruby 1.9.3
