hanging an oracle process: easy as that

Because it's labour day, I did some work on meta-pl/sql again. It was refactoring time and soon I will add another language feature - macros. But that's another topic.

Due to a silly typo, I had a hanging oracle process (one of the nasties where "alter system kill session" does not work):

create or replace package hang as
  subtype t is hang.t;

So it was time to freshen oradebug skills.

I only tested the hangs on my local development machine (11gR1 linux), but remember similar troubles due to dependencies between views and packages on other releases, too.
