Off list I got a tip on using become_user(). A soon as I get a grip on how
to extract the calling user's vuid I give it a try I have of course tried
other functions; become_user_permanently( ), become_user_by_session( ) and
become_authenticated_pipe_user( ). None of these have given the right
$HOME.Or I simply don't know how to interpret the outcome or to proceed
