Seeing this problem also made me very uneasy, but I was able to
reproduce it locally in a 64-bit VM with only 2GB RAM, and increasing
the memory to 4GB or enabling swap made the problem go away. So I
think it really is just a case of running out of memory.
Running sessionInfo() before creating the vignette is fine. I did try
inserting a call to gc() before sessionInfo(), and fiddling with the
value of R_MAX_VSIZE, but neither helped.
