I found an XP system that hadn't been upgraded in a few weeks, and I 
upgraded libglib2.0_0 but nothing else.  This was enough to trigger the 
problem.  I can reliably reproduce it as follows:

1. Start the X server (on an XP system) via the Start Menu shortcut.

2. Install emacs-X11-23.4-2, and start emacs under X.

3. Type 'C-x b RET' to switch to the *scratch* buffer.

4. Press and hold one key.  It echoes once, but the "repeated" key 
strokes don't get echoed until you release the key.

Fortunately for emacs users, the problem doesn't seem to occur with 
emacs-24.  (Can anyone else confirm this?)  But that doesn't help the 
gvim users who have reported similar problems.

Yaakov, could you take a look?  Maybe you could also make the previous 
version of libglib2.0_0 available so that users can downgrade until this 
gets resolved.

BTW, I installed the latest Cygwin snapshot, but that didn't help.
