Really? Three questions about that:

1. this was an IOError raised in start_response ... that seems to me like
it happens (a) when the app tried to write to the client, not (b) "as soon
as" the client disconnects. Did you mean uwsgi does (a), or does it really
do (b)? How? By a signal?

2. if (b), does that work via nginx too? I.e. as soon as nginx gets the
disconnect, it tells uwsgi, and the worker aborts whatever it's doing? Or
does this happen only when uwsgi serves http itself?

3. also if (b), can my python app get a signal about this immediate request
end, that it can use to abort back-end resource use, say a heavy DB query?
Does this require me to run threads/gevent, or could I just
uwsgi.cache_set(os.getpid(),
backend_id) whenever I start a possibly heavy backend query, and then uwsgi
would call my callback function worker_aborted(pid) where I would pull the
backend_id out of the uwsgi cache and tell my backend to abort?

Or am I misunderstanding completely? :)

Thanks,
