This reminds me of something suspicious in ZODB code.

Hi. I Use eye to browse the ZODB database. There, the methods of the float
object or any normal class objects are also shown. Are these methods stored
in the database?
Besides doing the _p_change magic, is there any extra advantage to write
class derived from persistent.Persistent? Does ZODB store

The ZODB basically does only append to the database file (Data.fs).
Only packing (e.g. through zeopack) will write a new (and smaller)
Data.fs file containing the referenced "life" objects.

1. zeopack the database
2. rm -f test.fs.old
Am I right?
