This readme contains a list of known issues:

http://lorentey.hu/downloads/emacs/multi-tty/README.multi-tty

For convenience I paste the Known Problems list here:

Known problems:

        * GTK support.  If you compile your Emacs with the GTK
          toolkit, some functionality of multi-tty will be lost.  In
          particular, you will not be able to work on multiple X
          displays at once.  Current releases of GTK have limitations
          and bugs that prevent full-blown multi-display support in
          Emacs.  (GTK crashes when Emacs tries to disconnect from an
          X server.)  Use the Lucid toolkit if you want to see a
          complete feature set.

        * The single-kboard mode.

	  If your multi-tty Emacs session seems to be frozen, you
	  probably have a recursive editing session or a pending
	  minibuffer prompt (which is a kind of recursive editing) on
	  another display.  To unfreeze your session, switch to that
	  display and complete the recursive edit, for example by
	  pressing C-] (`abort-recursive-edit').

	  I am sorry to say that currently there is no way to break
	  out of this "single-kboard mode" from a frozen display.  If
	  you are unable to switch to the display that locks the
	  others (for example because it is on a remote computer),
	  then you can use emacsclient to break out of all recursive
	  editing sessions:

		emacsclient -e '(top-level)'

	  Note that this (perhaps) unintuitive behaviour is by design.
	  Single-kboard mode is required because of an intrinsic Emacs
	  limitation that is very hard to eliminate.  (This limitation
	  is related to the single-threaded nature of Emacs.)

	  I plan to implement better user notification and support for
	  breaking out of single-kboard mode from locked displays.

	* Mac, Windows and DOS support is broken, doesn't even
  	  compile.  Multiple display support will probably not provide
  	  new Emacs features on these systems, but the multi-tty
  	  branch changed a few low-level interfaces, and the
  	  system-dependent source files need to be adapted
  	  accordingly.  The changes are mostly trivial, so almost
  	  anyone can help, if only by compiling the branch and
  	  reporting the compiler errors.
