FTR, the longer explanation is that GTK+ originally didn't have the
ability to connect to multiple displays, so that was missing from the
GTK+ build of Emacs for a long time.  At some point in the GTK+ 2.x
release cycle (2.6 or 2.8, AFAIR), such a feature was implemented, but
people soon discovered that closing a display would cause a crash in the
toolkit.  That was actually fixed for a couple of releases but soon
reappeared, after which their developers stopped wanting to fix that
bug.
