If I understand this correctly, it's specifically doing a halt with interrupts disabled. In theory that should just halt the processor indefinitely, since interrupts cannot be received. I can't imagine this being a common scenario for any software other than when it is completely shut down, unless of course you are explicitly expecting a non-maskable interrupt, which cannot be disabled, during a halt instruction. Again, I don't think it's all that common.

only very rarely happens, for example when shutting down the machine?
I don't think that is a very realistic assumption.
