Comment 13 for bug 1530518

There are 2 more sys.exit(0) calls in the code, and they need their del indexer as well. Indeed, we keep getting the error message despite the presence of del indexer before the sys.exit(0) at the end of the file. Adding del indexer to the other 2 fixes it.

... and possibly the two sys.exit's with non-zero exit-status need it as well.
