you could try to place a break at the start of swank::close-connection% to see what's triggering it
Thank you very much, I'm closer now (although it doesn't work normally yet). If I put a break at the start of swank::close-connection%, Emacs shows the debugger right after I connect to swank; then (and this is strange), after a few seconds, the REPL shows up in the other half of Emacs, and it works!! So, I have now the debugger open, and a functioning REPL (until I continue from the break); but the open debugger doesn't stop the REPL from functioning, and on conditions on the REPL, another debugger instance will show, so I can fully use the REPL. Now I'll need to examine the backtrace carefully... Thanks again, Paul
