10525	Outbound connect(2) failures are not propagated to guest correctly => Fixed in SVN	reidpr		"Steps to reproduce (see also notes below):

1. Install a Debian Wheezy 64-bit guest on a Mac OS 10.7 host.
2. Configure a NAT network interface.
3. Install links in the guest.
4. Locate a server which gives a ""destination unreachable"" error when pinged from the host.
5. Inside the guest, try to use links to access that server: ""links http://example.com"".

Expected behavior:

* links immediately displays a ""connection refused"" error (i.e., the same as what the host does)

Actual behavior:

* links waits until the connection times out and then displays a timeout error
* netstat shows the connection in SYN-SENT state until timeout

Workaround:

* Packets to the host in question can be rejected inside the guest, e.g. ""route add -host x.y.z.w reject"".

Notes:

* I hypothesize that the ICMP packet reporting the problem is not being passed to the guest.
* I suspect the precise details of which Linux are installed as the guest aren't important.
* I also suspect the problem can be reproduced with a simple connection refused from a reachable server, e.g. ""http://google.com:9999"".
