One thing which annoys me about emacs is that it doesn't do threading or non-blocking i/o when saving a file.

If I save a file on a remote machine (sshfs mounted), it stalls the entire interface. I only use emacs, so I don't know if "modern" text editors are better at this, but I certainly expect them to be :)

ST3 is no better at this, IME. When I edit files over SSHFS it at least freezes the file that's being saved, and maybe other files too.
