In a compute-intensive application, it is sensible to close the TCP
connection after you have communicated the job. Keeping the connection
alive is important to avoid the TCP connection setup, however, that is
neglible if you spend several minutes or more in computation.

I don't actually know how grid computing protocols work, but I believe
they are not concerned about networking performance, as they use HTTP
and SOAP to communicate jobs.
