Deadlock problems with send function (wodWebServer / wodWebServer.NET)

Hello,
I'm using the SSH.net component for Telnet and SSH communications.
I'm using a none blocking type, and I get very bad results when using Telnet protocol.
I have a textbox with a KeyDown event, and when ever I press a key for a few seconds (and calling the SSH.Send(..) function for each event) my main thread gets blocked.
When looking at the stacktrace, I get:

I would appreciate your quick response.
