That fixed things, thank you.

So, nginx+KQUEUE+SPDY breaks clients which shutdown on the write side,
without the ability to disable treating this as a client abort.

I'll sacrifice SPDY for now, to have correctness for existing clients.

Do you think that the SPDY patch will change to include something like
proxy_ignore_client_abort or will write-shutdowns just be treated as

Given that SPDY requires SSL which inherently requires bi-directional
connections at all times, the current behaviour with the SPDY patch is
absolutely correct, if SPDY is enabled for that server.  In this case,
it's a cleartext server so SPDY wasn't enabled at all.

[I'll reply to the list administrivia issue in a second email.]
