   job is created in a process

>> job.result = system(job.cmd)   #=> job.result has a value here

   you modify `job' in *another* process

>> job.result                      #=> job.result is empty. Why?

   you retrieve the value that was assigned in the initial process

   `job' is not a shared variable
