I don't recall. I believe so. If a client is dead, then there will be
a (-) is the cpids line at the bottom. If the client thinks that the
server is dead, it is quite possible that it will retract the socket
from the kernel ... and that makes slot->file null, and that in turn
ensures either a (.) or (-) in the printout, depending on whether it
was the last slot tried or not. I.e. (-) always has been the normal
indication of "no connection", and it has only shown as "(.)" when it
is also the only possible connection. Good connectons are shown as
"(+)" and "(*)".

Interesting. Let me know of problems. If you write up the
configuration, please let me have a pointer.
