35636 - network connections are not properly closed

Status: VERIFIED INVALID

(Core :: Networking, defect, P3)

On the nightly with build ID 2000041205, you only need to load a small number of
websites before this becomes really evident. Mozilla isn't properly closing its
network connections. Once enough are open, you get a TCP - Not enough memory error.

netstat gives a whole lot of lines like the following:

TCP	(my hostname:port)	(remote address:80)	CLOSE_WAIT

After exitting Mozilla, all the connections will disappear from the netstat listing.

As a followup to this, the number of still active connections balloons much 
faster in the original window than in any new windows, although it will still 
slowly increase as you browse in them.

I don't think it's relevent, but the TCP Error: Not enough memory only comes up 
once there are 93 network connections.

This remembers me of bug 35150, but that is marked fixed 4/11.
Maybe this fix has something to do with this...

Actually it will keep up to keep-alive.max-connections (default is 30) open
connections in the keep-alive queue. So, it's normal (there was a leak before 
which was fixed).

verified, since today's 10am build no longer has the problem.
