Public bug reported:

Xenial's emacs24-common contains a version of tramp.el which attempts to
ssh to host.does.not.exist on load which causes loading tramp to stall
until this hostname resolution fails (10 seconds for me).  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.
