Sorry if it sounded like the archive was the problem - it was holding 7000 
samples in memory in a std::vector along with all the other stuff the 
creator program also holds in memory that was the issue. So I needed to move 
to only holding one sample in memory at a time.

OK.

Actually, adding a terminator value for the Sample class took 15 minutes and 
worked first time. So perhaps it is less fuss than I originally thought to 
add it for each class I want to archive in an open-ended list like this.
