Context Connection And Command Timeout

Hello,

I'm using a context connect inside a CLR stored procedure. The CommandTimeout property has no functionality when used with a context connection. See remarks in this url:
http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.commandtimeout.aspx

This is a problem for me because I'm at times call a link server that has been known to wait indefinitely. I've tried using a regular conneciton that supports command timeouts within my CLR stored procedure but I get a permissions error (Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0,0, Culture=neutral failed.)

How can I prevent my CLR stored procedure from waiting indefinitely?

Thanks.
