After well into the second decade of slime-disconnect/slime-connect loop iteration (interweaved with normal operation) the emacs side of slime stopped recognising connection status.
I`m doing a slime-disconnect, restarting swank and slime-connect, however immediately after this either a slime-load-file or a (load ...) in slime repl result in a message "Connection closed."
i have some time before i will have to reboot the machine, and until then i can provide various forensics upon request...
