Possible it is, but probably harder than just doing what they said

I would like to know from where does it get that info? I would guess  
from "__module__".

Why doesn't zodb has a table of some form for this info? I heard that  
sometimes for very small objects the string containing this  
information can use up to 30% of the whole space of the file (using  
FileStorage). How does RelStorage store this?

ps: I should probably look around on code to find this, but I'm asking  
so that I know why it was made the way it is.
