[libvirt-users] Detecting the last user of a connection has closed.

The documentation says something that concerns me:
http://libvirt.org/html/libvirt-libvirt.html#virConnectClose
"It is possible for the last
virConnectClose<http://libvirt.org/html/libvirt-libvirt.html#virConnectClose>to
return a positive value if some
other object still has a temporary reference to the connection, but
the
application should not try to further use a connection after the
virConnectClose<http://libvirt.org/html/libvirt-libvirt.html#virConnectClose>that
matches the initial open."
The application I am working on requires that I know when the last thread
using this connection goes away, so I can properly cleanup some overhead.
If I can't trust the return value of this call, how will I know that the
connection is indeed torn down?
Under what circumstances will the virConnectClose behave this way?
Thanks,
BTW, I am using 0.8.2
