You reminded me of these comments on a bug in NVidia's Tegra
"Project Denver" dynamic JIT firmware:

Lest you think things are better now, Linux uses
self modifying code to
optimize certain critical operations, and at one talk I heard the speaker
say that he'd like to put more self modifying code into Linux, "because
it's
fun". Oh boy.
Fun, indeed! Even self-modifying chips are being touted -- Yikes!

This happened with TransMeta back in the day, and now with Tegra. I
wonder if NVidia has a update deployment strategy...
(Marginally topical relevance is that Linus Torvalds worked for Transmeta)
