From time to time the windows slave is closed.

Slave reports:
> SEVERE: I/O error in channel channel
> java.net.SocketTimeoutException: Read timed out
> at java.net.SocketInputStream.socketRead0(Native Method)
> at java.net.SocketInputStream.read(Unknown Source)

Two slaves are started on this machine. It happens that only one is closed so I doubt that this is a network problem...
