Make sessions run in it's own thread
What I notice on Windows is that when I open more than one ssh session that's constantly having terminal activity (logs or htop), that other sessions start lagging quite badly. If I close those active sessions it's back to normal. If each session would start under it's own thread I'd never have this issue. It's quite annoying to have to close and reopen sessions just because terminal text in other sessions affect a different one.
