Note that Zope2.app() opens a new ZODB connection which you need to
close at some point. I suggest something along the lines of:
app = Zope2.app()
try:
products = app.Control_Panel.Products
...
finally:
app._p_jar.close()
I am also wondering if this code would break if a product was removed
from the file system, but still had its persistent part hanging
around in Control_Panel.Products.
