I believe it would be better if the internal code forced the promise
at this point. I'll have a look; there may be a few other similar
instances worth looking at.

Thanks! That is exactly what I did
(https://github.com/yihui/knitr/blob/master/R/cache.R#L44) but I was
wondering if .Random.seed could be better recognized when it is lazy
loaded.

You can remove it by a simple assignment:
.Random.seed <- .Random.seed
will do it. (The reason is that it doesn't copy the object blindly, it
evaluates the RHS to get 1L, and it's a regular assignment, so that gets put
into the LHS.)
