Intermittent time-outs

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an HTTPWebRequest (in .NET)
2. Call GetResponse()
3. Boom...

What is the expected output? What do you see instead?
The expected output is a response stream, but instead an exception is triggered.

What version of the product are you using? On what operating system?
.NET 4, Windows 7 (not that I think it matters for this issues though...)

Please provide any additional information below.
It only happens intermittently. This morning I ran it 4 times, the first 3 
failed and the next worked. It did make me realise my architecture wasn't ready 
for certain exceptions though, so I am fixing that - at least something good 
has come from it ;)
