That sounds like a hardware problem. Does Console.app show anything in
the system or console logs around the time of death?

Yep - very well could be video hardware going south. In fact if he's got
NVIDIA graphics and this is a laptop, I would be very suspicious of the
video hardware. Even if it's purely hardware, though, I would still
expect (or at least hope) to find something in the /var/log/system.log
indicating problems. It's definitely worth a look.

Not long after I posted the above I undertook a number of
"housecleaning" actions, repairing disk, repairing permissions, and
emptying a bunch of caches, and since then the oddities I described
have not yet reoccurred.

I'm crossing my fingers! :-)

Frequent beach ball of death in Safari here too. I just installed Snow
Leopard yesterday and had absolutely no issues whatsoever in 10.5.8 (Mac
Pro quad core, 8 GB RAM). Definitely not a hardware issue. This is
starting to really aggravate me.

My daughter says she is also getting the same kind of freezes in Safari
on her iMac (core 2 duo) in 10.5.3. Agh... I wish she had told me
before I went ahead and installed Snow Leopard on mine. (I did hers
first)
