What is the currently implemented behavior of the remote stream in swank when the net connection breaks? I started a long running function and at some point the network went down. The remote lisp is still running and I managed to reconnect through tty because it was running in "screen". I am trying to restart the swank server. I am just wondering if swank thread is still running or is blocked on output. Is there a way to reconnect, like in 'screen. This is in allegro CL.

In theory, all swank threads should be killed and all swank streams should be closed. It's not easy to handle errors across multiple threads, so I don't know if the current implementation actually does what it should. We had many bugs in this area, and I would be surprised if we fixed them all.

You could try swank::restart-server and after that M-x slime-connect.

If all swank threads are killed, that means that whatever calculation was running is killed too, right? So, reconnecting is pointless.
I was hoping for a functionality like "screen", where even in case of a loss of connection, the virtual tty stays up and one can reconnect to the still functioning tty.
In other words, if I make a function call in repl, which may run for 10 hours, I don't want to lose my calculation in the case of network outage.

If you spawn your own thread, swank doesn't know about it and won't kill it. But you are right, SLIME has no "detached" mode.
