That gives 12 files, yes. But there's no reason for it to use 12  
\write streams. Just close the streams at end of chapter, and re-open  
with new filenames for the next. So 3 streams are enough for such a  
package to handle any number of chapters, even without interleaving  
the records in a single file and then distinguishing them as they're  
re-read later.
