OK, that also fits with my observation that for several of the
files, coordinates are 0. But then how can there be files from three
(or more, for Aldo's system) different time steps? Is that because not
all CPU's decide at the same time that a crash is in progress (i.e.
they each decide for themselves, and may 'disagree')?
