Not really long, the main stuff that is on your Ubuntu might work. I
heard that under heavy load you can see some random problems but i've
used PaX for some time on mid load servers without breaks so your
desktop should be ok (really).

Add on the list: Java (jvm, of course not in main) and Wine (universe).
