notes:
os is different for Windows. os.setsid does not exist in Windows.
preexec_fn=os.setsid now implemented by setting start_new_session=True
from the subprocess documentation
Note If you need to modify the environment for the child use the env parameter rather than doing it in a preexec_fn. The start_new_session and process_group parameters should take the place of code using preexec_fn to call os.setsid() or os.setpgid() in the child.
/bin/bash is not OS agnostic, and executer now specifies sh which should be a predefined alias if bash is supported
