This is not a solution.  Some window managers (fvwm at least) lets you
move in short increments towards the next workspace.
If what we see is workspace 1 it kind of looks like this (M is a menu):

   ------------------------------
   | workspace1   | workspace2  |
   | ----------   |             |
   | | M      |   |             |
   | | Emacs  |   |             |
   | ----------   |             |
   ------------------------------

By using ALT-Right arrow one can move the Emacs gradually towards workspace 2

   ------------------------------
   | workspace1   | workspace2  |
   |       ----------           |
   |   M   |        |           |
   |       | Emacs  |           |
   |       ----------           |
   ------------------------------

so what you see is part of the Emacs main window, but the
menu is left behind, outside the main window.  In no situaton is the Emacs
window unmapped.  Thus, a keyboard grab to prevent this is the only solution.
It what other applications (X toolkits really) do.
