[nginx] svn commit: r4349 - in branches/stable-1.0: . src/http

[mdounin at mdounin.ru]

Author: mdounin
Date: 2011-12-13 18:30:15 +0000 (Tue, 13 Dec 2011)
New Revision: 4349

Log:
Merge of r4144:

Upstream: clearing of u->peer.connection on close.

This fixes crashes observed with some 3rd party balancer modules.  Standard
balancer modules (round-robin and ip hash) explicitly set pc->connection
(aka u->peer.connection) to NULL and aren't affected.
