Another thing which may cause an unpredictable amount of frustration
is when you forget "quoted form" before calling rm.
Also, I would have thought that "rm" without "administrator
privileges" would leave /System untouched? Maybe also iTunes, in order
that you still be able to make purchases... :-)

Previously, if you concatd various commands in the same do shell

I can't remember, but it surprises me to think that it has changed.
I also noticed that now the default path in do shell script is the
root:
----------------
do shell script "pwd"
--> "/"
----------------
I don't think that's changed, either (actually, I believe it
inherits the
path of the process calling it).
Now, let's combine both new behaviours and see what happened in my
comp two
days ago, when I was running some tests:
----------------
do shell script "cd /bogus/path; rm -rf"
----------------
Result: delete everything in the boot disk.
Again, I'm not sure that's new. I have a very, very good friend,
ahem, who
got bitten by that very thing a couple of years ago. Very
embarrassing :-(
Another thing that's not new but can result in unexplained behavior:
if you
hit the escape key at the time your app is calling do shell script,
the
process will terminate immediately.
