Comment 24 for bug 1669578

So, Stéphane brought to my attention that we're not including the patch because it switches screen to use sockets instead of fifos and thus makes it impossible to switch to existing fifo-based screen sessions. I've written a patch that adds a compatibility layer to support both fifo-based and socket-based screen sessions. The idea is to only re-use existing fifo-sessions but never create new ones. All new screen sessions will be socket-based.
