My understanding is that an open of /dev/w? will *always* fail if that
window is not in use. If you're not using /dev/w2, try
echo hello >/dev/w2
from the shell. I betcha it won't work. You have to open /dev/window, then
the window manager *hands you* the window number. The fact that "/dev/window"
shows up in your strings listing makes me think the author of wsdb *had* to
have understood this. Maybe it's getting the wrong idea of which window the
window manager handed it.
I guess this doesn't help you much ...
