[restart] in fluxbox menus

Hi,

I'm very interested in the "[restart]" menu item.  I'm interested in
the fact that it can cause fluxbox to quit while handing over control
to another window manager.

I was wondering if there other window managers that were so gracious in
giving up control to fluxbox.  I've noticed over the years that some
window managers have a command-line option called "--replace" to allow
them to take over from another window manager, but fluxbox isn't one of
them.  

I was wondering if anybody knew of other window managers that can give
control back to fluxbox, as well as hearing any general ideas people
have about window managers that work well with fluxbox.  Any help for
me on this would be appreciated!
