Phoebus' PV close() calls?

[William F Badgett Jr via Tech-talk <tech-talk at aps.anl.gov>]

I have written a Phoebus plug-in for Fermilab's existing control system.   To minimize computing and networking resources, I only create one PV object per device.  Is that standard practice?    My concern is that when a display is closed by the user, Phoebus may call the close() method while other widgets are still listening to that same object.

Thanks
