As far as I can tell, you will have to restart the server in order to
be alowed
to run mwm again.

WM_nn (wherw "nn" are screen numbers) are "selections". They are used
by
mwm as locking mechanism ensure that only one window manager has the
control over each screen. In normal operation, quitting mwm should
remove
them but if it crashes then they are kept on X the server.

For more informations about selections, see

I hope this helps.
