The fix referred to earlier is against emacs 25. There appears to be no backport of the patch in the emacs24 tree, so I have rolled my own patch, based on the fix for emacs 25: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=20015. I've created a deb and checked that it works. If the emacs package maintainers can just incorporate this: great. If not, I suppose I could try to upload the deb to a ppa, though I'll need to work out how to do this.

This makes my emacs startup (I load tramp via other libraries which use it) take about 12 seconds, instead of a fraction of a second like it should be. Upstream maintainers seem to have fixed this to attempt ssh to 0.0.0.1 instead, see the git log output attached.
