haml plus kill-rectangle hangs emacs

[Audrey Lee <audrey.lee.is.me@gmail.com>]

Hello emacs people.

I have bumped into an issue with emacs when I try to kill-rectangle
inside a file which is in haml-mode.

I see 2 symptoms:

1. Emacs "hangs"
2. The emacs process start hogging 99% of the CPU on my Mac.

Here is info about my emacs:

GNU Emacs 22.3.1 (i386-apple-darwin9.6.0, Carbon Version 1.6.0)
 of 2009-01-02 on seijiz.local

Question 1:
  - In my .emacs, What might be some simple syntax I can use to
disable kill-rectangle while I am in haml-mode ?

Question 2:
  - In my .emacs, What might be some simple syntax I can use to
connect a key to a function, but only for haml-mode, not globally.

Question 3:
  - Does emacs have some kind of debugger I can use to tell me what
files it is reading when I execute emacs commands?

These are the only emacs questions I can think of today.
