Windows 2000 is no DOS, so IMHO 'plays it so safe' is something else,
namely, how good w2k virtualization/emulation of some feature is, no
matter how 'nice' or 'good' that feature is in the real DOS...

OK, enough of theories, here is one checkpoint i've hit:

------8<-----------------------------------
--DD\---F1  *scratch*         (Lisp Interaction)--L5--All-----------------------
M-x tetris
Breakpoint 1, Fexecute_extended_command (prefixarg=270752772)
    at keyboard.c:9314
9314      real_this_command = function;
(gdb) n
9317      if (!NILP (Vsuggest_key_bindings)
(gdb)
9320        bindings = Fwhere_is_internal (function, Voverriding_local_map,
(gdb)

D:\devel\djgpp\gnu\emacs\BIN>
------8<----------------------------------

Now that keyboard.c:9320 line is the one causing aborts every time.
I'll dig further now. I'm sending this just to check it it doesn't
ring any bell to you?
