Burning CD/DVD, starvation, doesn't use burn-proof

Bug Description

Binary package hint: k3b

If I'm burning a CD or DVD using k3b, and something happens that requires a lot of disk of CPU access, k3b does nothing to recover.

First problem: k3b isn't given enough priority to prevent starvation.

So while burning a disc, I decided to start some other program. Stupid thing to do? Maybe, but k3b should have recovered. Instead, the drive itself quit burning.

Second problem: k3b doesn't notice that the drive quit and "keeps going" with the progress meter going along as though nothing happened.

So, the burn-proof option is useless to k3b because it never recognizes when a problem has occurred.

Naturally, during verify, the disc was found to be corrupt.

 Have you had this happen with CDs and DVDs? I thought DVDs were smarter about recovering, and were supposed to be able to. It didn't take a special feature like "burn proof".

 I'm not sure if I've ever had a buffer underrun while burning, but I think so, and my discs come out ok. (I've sometimes seen single-bit errors on them, though, which is why I always make par2 files to put on the disc with the files. This is easy if its a few big files, which is what I'm always burning.)

One can work around this issue by making wodim setuid (not recommended in the general case) or by burning at a slower speed.
