Issue with 1.0.4 connector - Cannot access a disposed object named "System.Net.Sockets.NetworkStream".

[James Moore]

Is anyone else seeing an issue with 1.0.4 and pooled connections running
under IIS?  I saw a message from Jean-François Mathieu from a few weeks ago,
but it didn't get any responses, and the bug I found (7246) is marked as
'can't repeat'

At this point I have no reason to think it's not a problem in my code, but
I'm not doing anything to manipulate the connection pool directly.  I
thought I'd check and see if anyone else has seen anything similar.

Here's the text of the error I'm seeing as reported to an HTTP request:


Cannot access a disposed object named "System.Net.Sockets.NetworkStream".
Object name: "System.Net.Sockets.NetworkStream". 
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
