Hangup effect

[mikeplavsky]

I see two issues with powerslim code which can lead to hangup effect:

This code does not have any checks or error handling for the situation when port is busy:

    $ps_server = New-Object System.Net.Sockets.TcpListener($args[0])

It means that based on these specifications:

http://fitnesse.org/FitNesse.UserGuide.SliM.SlimProtocol
http://fitnesse.org/FitNesse.UserGuide.SliM.SlimProtocol.PortManagement

Fitnesse will start SlimServer and will be waiting probably forever till SlimServer sends Slim Version string

The second problem is with this code:

     $ps_fitnesse_client.Client.Poll(-1, [System.Net.Sockets.SelectMode]::SelectRead)

It does wait forever till Socket gets into the reading mode. IMHO waiting time should be restricted by time out.

I would start with the appropriate logging into file around the problem areas. Then we could detect what really happens.
