A reincarnation prototype for the Hurd
======================================

% ./reincarnation -c hi ./persistent-hello --content="hi there :)
" &
% cat hi
hi there :)
% pkill persistent-hell ; cat hi
hi there :)

!!! run as root, libtrivfs allows only root to do this atm :(
# fsysopts hi "--contents=something else
"

% cat hi
something else
% pkill persistent-hell ; cat hi
something else

Whoa, persistent-hello got reincarnated and retained its
state. Unfortunately any client related state is currently lost,
including the ports:

% ( pkill persistent-hell ; cat ) < hi
[1]    14400 resource lost  ( pkill persistent-hell; cat; ) < hi
