The same problem is faced on an upgrade though.  It's a general issue
in configuration/namespace management, and this particular scenario
points out a defect, or lack of functionality, in the infrastructure
design.  For example, in the GNU/Hurd one can send messages to
processes to update their environment variables at run time.  That's
not a proper solution (at all), but it points into the general
direction of a potential solution here (namely the ability for
processes to communicate and exchange information about changes in the
configuration).  Of course, all projects from a certain size up face
these or similar challenges, and have work-arounds of various degrees
of ugliness.
