Title: JRuby 1.9 compatibility

Tests are not passing on JRuby

jruby --1.9 -S bundle exec rake

On JRuby 1.9 there is some problem with:
pid = spawn("ls"); p pid; Process.waitpid(pid)
Errno::ECHILD: No child processes - No child processes

jruby --1.9 -S irb
require 'subexec'
Subexec.run('ls')
...
LocalJumpError: break from proc-closure

Thanks to posix-spawn it's getting better!
