* if run by root (or root process) drop privs
* ensure output size is not infinate (net finger only)
* ensure output lines are not infinate in length (net finger only)
* do not allow finger client to run longer than 3 minutes (net finger only)
implementations to leave the client side open until the server closes.
While this is totally idiotic, it seems as if some servers actually require
it (e.g., the one at mit.mit.edu). So, we bow to the weight of the bogus
standard and disable the initial close. Hopefully now fetch(1) can serve
the role of T/TCP demonstration application.
