It's all explained in the comment a few lines above where ob_sinterned 
is used:
	/*
	** If we have interning find_module takes care of interning all
	** sys.path components. We then keep a record of all sys.path
	** components for which GetFInfo has failed (usually because the
	** component in question is a folder), and we don't try opening these
	** as resource files again.
	*/

This code gives a considerable speedup for module searches. The reason 
it's mac-specific is that MacPython allows files on sys.path as well as 
directories (and these files are searched for PYC resources).
