Hmm. The "move .RData before writing to it" fix didn't seem to make
it. It's a one-liner (in the most primitive version), and really quite
important. Actually, the problem is worse than I thought initially:
.RData can get zapped to a zero-length file whenever you destroy the
xterm window containing R, not only on system shutdown. This happens
on both of my Linux boxes, but it's probably a quite generic race
