Why is it difficult? If you have a python script such that

	python mytests.py

loads the .so and runs the tests, then

	valgrind --tool=memcheck python mytests.py

should work. This should immediately spit out an error in case that 
numpy accesses deleted memory.

Of course debug information should be enabled when compiling the .so for 
more useful output, and it could be helpful to have it for numpy/python, 
too, but that's not a requirement.
