Eh, what's wrong with simply using __file__? It's a global in your
own module, remember!

One more refinement: instead of os.path.split(x)[0], use
os.path.dirname(x).
The whole thing could become a one-liner:
_thisDir = os.path.dirname(__name__ == '__main__' and sys.argv[0] or __file__)
You could also use the little-known fact that sys.path[0] is the
script's directory; or the empty string if it's the current directory:
if __name__ == '__main__':
_thisDir = sys.path[0] or os.curdir
else:
_thisDir = os.path.dirname(__file__)
