[Zope] Announce - Audio Product

[marc lindahl]

I don't think it ever did this.  From looking at File, which Image and Audio
are both based on, it has this data type called Pdata().  It uses this
whenever the data size is larger than 2^16 (an arbitrary number buried in
the file).  What that does is, it chops the file into chunks (of, I think,
2^16), and builds a linked list of them.  Then when it stores or retrieves
the file, it only has one chunk in memory at a time.  Same when it renders
it, it writes it out one chunk at a time.  Take a look in OFS/Image.py at
the bottom of the file.

Anyway, memory is cheap :)
