I still keep getting hung sessions while trying to exit.  For example
just now, with a recent version of Emacs under MS-Windows:

In GNU Emacs 24.4.50.1 (i686-pc-mingw32)
 of 2014-06-15 on LEG570
Repository revision: 117347 rgm <at> gnu.org-20140615175930-x692pxm647xqo0et
Windowing system distributor `Microsoft Corp.', version 6.1.7601
Configured using:
 `configure --enable-checking 'CFLAGS=-O0 -g3' CPPFLAGS=-DGLYPH_DEBUG=1'.

I've been able to attach gdb to the hung process, and get a full
backtrace (see below).

I will leave the session open, in case you need me to print some values.
