LR 1.1 Crashes: Is Bonjour to blame??

Question

I posted earlier about my frequent crashes specifically on rating photos in the library module:
http://www.adobeforums.com/cgi-bin/webx?128@@.3bc4644c
Tried upgrading/changing RAM and many other things (including driver updates) but never was able to get through more than a few photos before a crash.
As one step, I decided to go into msconfig (I'm on Windows XP sp2 by the way) and disabled all unnecessary Startup and Services. Found one in particular that puzzled me called:
##Id_String1.6844F930_1628_4223_B5CC_5BB94B879762##
Checked with Google and learned this was part of the Bonjour service that both Adobe and iTunes now use. After disabling this and restarting, I was able to process the next three photo shoots (about 200 photos) without a single crash!
Then I was working on 120 photo shoot one night while listening to Harry Potter on iTunes and got repeated crashes. Restarted the computer and tried again (with iTunes on) and crashed again - just like the bad old days. Gave up and went to sleep and listened to the rest of the chapter on my iPod. Next evening, I repeated this only without iTunes on and I was able to rate all photos without a crash!
So, for all those who know the inner workings of these programs better than I do, does this behavior make sense? Could Bonjour be responsible?
For those with crashes, try disabling this program in msconfig and not running iTunes on a clean reset and see if this fixes your crashes.
Hope this helps (and I hope I haven't jinxed myself...)

I don't know Bonjour all that well, but there is another possible explaination. LR runs your system pretty hard, even when it is the only thing open. In fact it is the only program that really heats up my notebook.
If you have it open at the same time as Photoshop or a word processor then they are not necessarily working at full speed at the same time. With iTunes running in the background (or any audio player) it is going to be using some of those system resources that LR wants all to itself.
Same priciple as getting disk writing errors when working the processor while burning a disk. Just a thought. It's why I use my iPod while editing photos, instead of iTunes.
