8.0.1. update + security update, now I can't restart my MacPro?

Question

I ran "Software Update", it found a Logic Studio 8.0.1 update and a security update.
I click Install 2 Items
It downloads and installs and then prompts me to restart.
I click Restart and nothing happens -- my system doesn't restart?
So I try to "Shutdown" and after several minutes of nothing at all (not even a processing rainbow), it finally comes back saying it can't shutdown because my Email is still running.
So I click quit on Email and try again, once again nothing.
So I'm stuck in a state where my MacPro will not shutdown nor restart. Any suggestions other than holding down the power button for 4 seconds?
Great job Apple, love these updates already -- ****! Where did you get the testers for these updates, 3rd grade school?

Answer 1

I found how to shutdown the OS without a hard power down.
Under the Apple icon (upper left corner), select "Force Quit..." -- it will list the applications currently running and I can select the "offending" application (in my case Email).
This got to a point where I could do a "safe restart".
I had left my Mac for 30 minutes to see if it would restart after the update, but it never did. Under Tiger the "Force Quit" option was available with a right click on the icon in my dock. Apparently under Leopard this has changed.
But the real issue here is:
1. Why did installing the LP8 update and 1 security update put me in this situation in the first place?
My guess is that NO ONE at Apple has a test system that represents a very common situation among users, those that updated from Tiger to Leopard without wiping everything out and starting from scratch. I'm almost positive Apple test on systems that have clean images and they just keep restoring the images to a clean state before each test. Which is completely NOT representative of the real world of users. In other words, very basic testing. I mean come on, the install goes out to lunch because I had my Mail program open. At the very least is should come back and say "please close XYZ program before continuing". I'm sorry but this is just SLOPPY work, very sloppy, and very unprofessional.
I've NEVER had a software update do this before! Sorry for my frustration, but I don't expect these types of problems on Apple's controlled hardware/software platform. On Microsoft platforms, sure I've learnt to accept it, but I expect more from Apple and pay more to Apple and in return I do expect it to "just work" (do what their ads claim).
