[chef] Parallel execute resource tasks

["Van Fossan,Randy" < >]

I have a recipe that has 4 disk tasks that each one takes about 10 minutes.   
I would like to execute the tasks with an & at the end to fork off the 
process and run them in parallel.  However, I am not sure how to track that 
all four are complete.

I suppose, I could loop, test and sleep for a file completed at the end of 
each task and then continue.   

Has anyone have any better suggestions for handling forked processes and 
tracking completion?

Thanks
  Randy
