New submission from Gabor Kovacs:
The attached script works in 2.6(.4) but not in 2.7(.3); the script cannot
locate its own source code if invoked by relative path and work directory has
changed. If line 8 uncommented, everything is fine due to caching.
I think this is related to issue #4050 changes in inspect.py.
