Letting go of the browser

A perhaps more important reason to use nph- occurs when you want your cgi script to

accept some user input (such as from a form)
start some long process (such as a model run)
tell the user the process has started
say goodby to the user

If you don't use nph- the server will (apparently) try to keep the connection with the browser open until your cgi script and all its sub-process of have completed. And if the person reading the browser presses the 'stop' button, the server will try to terminate your script and all its sub-processes (or rather it should!).
