Address in use

[ukkiwisurfer]

I'm getting a persistant issue under Windows 7, (CLR 4) that if I run unit tests back to back, I get an Address in use error when I attempt to bind a socket to tcp://127.0.0.1:9100. I am running v3 RC 1 of the library which I installed using Nuget package manager.

I am using a PULL type socket for the server node which is running in a dedicated Thread. If I run the unit test as a standalone test, it passes. (A message is sent from a client to the server). However if I run two tests back to back I get the above error.

I've identified that it is the act of Send or SendFrame that seems to give rise to the error. I am disposing of both context and socket as well as unbind on the server side, yet I still get this error. If I specify a NoWait option on the socket I don't get the error, but then again I don't get any messages either.
