Yes, I have read those docs as well as a couple of technical bulletins from
MetaLink. Bottom line is Oracle (especially pre-8.1) does a lousy job of
un-installing itself. The documented steps don't always work -- thinking
services are running when they aren't, leaving OS level locks on files so they
can't be deleted manually, trash left in the registry -- all kinds of little
'gotcha's that keep you from making the machine look like it never saw Oracle.
