ok I did not know that. feel free to ignore my comment.

I did not consider the garbage collection. I assumed that out_file would Always
be closed when it Went out of scope and then this would require less
indentation:
out_file = open(extern_fns_map_file, 'w')
for mangled_name, ast_file in mangled_ast_pairs:
out_file.write('%s %s\n' % (mangled_name, ast_file))

+ ctu_config = get_ctu_config(args)
+ if ctu_config.collect:
+ shutil.rmtree(ctu_config.dir, ignore_errors=True)

with "not a big deal" I mean; feel free to ignore my comment if you want to
have it this way.
