[plt-scheme] anyone written a web-server app that drops privileges on Unix?

I am not aware of a portable way of setuid on Windows, as you need to have
the password of the user in order to switch to that user.  The closest thing
that I came across is http://www.joeware.net/freetools/tools/cpau/index.htm,
which encrypts the credentials so you do not need to enter it everytime.
