Good thinking. I did another test, but am still finding a new JVM being
created.

I wrote a script, shell-out-test.rb:

puts "starting script and sleeping for 5 seconds"
sleep 5
puts "shelling out for 10 seconds"
`ruby -e 'sleep 10'`
puts "done shelling out, sleeping another 5 seconds"
sleep 5


Then opened two terminals side-by-side. In one I ran:

  watch 'ps aux |grep [j]ava'

In the other I ran my script:

  ruby shell-out-test.rb

And I observed two java processes running while shelling out.
