Well, you'll have to clarify what's so "terrible" about it. Note that I didn't
use os.path.isdir or similar because those functions hide all kinds of relevant
exceptions, such as EACCES.

If it's the continue and break that upset you, we can do it like this:

found_dir = False
while current_dir != os.sep and not found_dir:
	try:
		os.stat(current_dir)
		found_dir  = True
	except OSError:
		if errno == errno.ENOENT:
			current_dir = \
				os.path.dirname(current_dir)
		else:
			found_dir  = True
