Well, you certainly know how to interpret what you write and I
certainly didn't :)

hmmm... I've seen many fixes needed for several instruction sequences
which did not handle being interrupted (i.e. broken serialization);
unclear how many of the unrepeatable bugs are due to cosmic rays...
as a programmer I wouldn't want to assume that any of them
are... certainly the customers I'm familiar with would not accept that
as an answer :)
