-** Python modules are Mach-O MH_BUNDLE files. The best way to load these
-** is each in a private namespace, so you can load, say, a module bar and a
-** module foo.bar. If we load everything in the global namespace the two
-** initbar() symbols will conflict.
-** However, it seems some extension packages depend upon being able to access
-** each others' global symbols. There seems to be no way to eat our cake and
-** have it, so the USE_DYLD_GLOBAL_NAMESPACE define determines which behaviour
-** you get.
