Well, the question then becomes whether Popen() shouldn't use the user's
default shell instead? :)
It probably doesn't make much of a difference in most cases, though.
Also, there's the problem that some special users may have a void shell
entry (or /bin/false or /sbin/nologin), to prevent a human from logging
in as them.
