When you remove a product, all its instances will become broken (your zodb might contain such old instances even if unused). Or, if the product does some not-so-portable things like storing a full path to an external file as an attribute (there are some examples...) you'll have some problems if you install into another directory. But in general, if no such odd things happen, it's just "plug and play".

Try with zipefile.ZipFile(response,"a"),
this should avoid the use of tell (untestet)
otoh, If you'd use the tempfile module and
dont return f.read() but use FileStreamIterator
with it, you even have a win performance-wise.

RE: [Zope] Re: ZServer threads and pool-size question
I saw that once on Zope 2.8.4, cause I was using a connection in a independent thread not linked to any incoming request and had forgotten about it ;) Never since then, so it looks like threads = pool size is fine for my setup.

It depends on how intensively you are using additional (application level) threads: Each thread using persistent objects requires in general (at least) one ZODB connection.
