The standard Python functions for spawning child processes are
subprocess.Popen() and subprocess.call()

	http://docs.python.org/library/subprocess.html

The grass.script module has its own versions of these functions, which
set shell=True on Windows so that scripts work, but that doesn't
matter if you're running a binary executable. It also has several
functions which are intended specifically for running GRASS modules
(anything that uses the GRASS command-line parser).
