Maybe this is overkill but here is a bash script I've wrote to
forcefully restart BackgrounDRb:

#!/bin/sh

if [ -a "log/backgroundrb.pid" ]; then
  pid=`cat log/backgroundrb.pid`
  if [[ -n "$pid" ]]; then
    echo "Killing current BackgrounDRb server (pid: $pid)"
    kill -9 $pid
  fi
fi

echo "Starting the BackgrounDRb server"
cd /var/www/123/current
log="/tmp/backgroundrb.`date +%s`"
echo "Writing to $log"
nohup rake backgroundrb:start > $log 2>&1
cat $log
rm -f $log

It is derived from a script I found while googling, I don't remember
who it's from so I can't give credit.

Here's what I added to my deploy recipe:

task :before_restart, :roles => :app do
  sudo "#{release_path}/script/backgroundrb/restart"
end
