> Subprocess has problem when run in multithreaded environment. As stated by 
> developers it should not be used in such env.
> As a result Ambari done multiple patches to subprocess. However still we are 
> having multithreading problems with it.
> This jira targets moving from Subprocess to Subprocess32 (a port of Python3.0 
> subprocess) which support multithreaded execution.
