File upload and no blocking code is impossible (with linux kernel)
unless you store the file in a separate process or unless you use kernel
So either you use a sql db with "binary" field, or you have to store the
file using a "pb" server, in a separate twisted process.
Some discussion happend on twisted-python and it seems somebody is
working on it. I even considered writing a generic storage daemon that
would avoid the twisted core to block on I/O, but then I giveup
completely and I use only postgresql under Valentino suggestion, and it
works great ;)
