This is likely due to lingering close changes in 1.0.6:

    *) Bugfix: in closing connection for pipelined requests.

You may fine-tune the behaviour via lingering_close, 
lingering_time and lingering_timeout directives (see 
http://nginx.org/r/lingering_close), though I would rather 
recommend to keep the default.
