are two key things that were necessary:
1. We have to turn off the -fvisibility=hidden flag, since this hides the symbols in our
shared libraries from others. There's probably a better way to handle this, but this
is expedient for now.
2. Since I'm testing with GNU compilers & linkers, I have to use the magic lines in python
before importing the inter-dependent modules (see test_cross_module_inheritance.py):
import sys, ctypes
sys.setdlopenflags(sys.getdlopenflags() | ctypes.RTLD_GLOBAL)
This shouldn't be necessary on all platforms.
